Introducing DyaconLivePlus

By Blog No Comments


DyaconLive is an access-controlled weather station web portal for Dyacon weather stations. It shows real-time conditions, log charts, and local weather forecast. System status, alert emails, maintenance management system, specialized reports, and operational information are also available.

Quick-Read Summary

We are updating DyaconLive and segmenting it into a free, basic version and an advanced, paid version. DyaconLivePlus(+) will only be $2 per month for those using DyaconLive with a Dyacon cell phone service. Those uploading through secondary measures will also have access to DyaconLivePlus for $7 per month.

The Proposition

Over the years, we have invested tremendous resources into building a useful web portal for professional users. One of the challenges in business is knowing when to release a new product and at what price.

It’s now time for the delicate dance of segmenting DyaconLive into a Basic (free) version and a Plus version. If we do this right (and with your input), most users may not notice any difference. Our hope is that the more sophisticated features of DyaconLivePlus provide sufficient value to justify the minimal price increase.

The following is the proposal to be effective for the next billing cycle.

  • Cell phone with basic DyaconLive will remain unchanged at $23/mo
  • Cell phone with DyaconLivePlus will increase slightly to $25/mo
  • Secondary upload with DyaconLivePlus will be $7/mo.

These changes will help support the maintenance and ongoing DyaconLive service.

Compare DyaconLive and DyaconLivePlus

The following feature table compares the two versions. In general, most users of a single station will have the same functionality they are accustomed to. Users with 10 weather stations or more that are using cell phone connectivity and users of the white-label will not see a change.

Transition to DyaconLivePlus

To minimize the disruption to our customers, DyaconLivePlus will transition over several months.

We welcome any feedback. Our intent is to balance user needs with Dyacon needs in a way that is mutually beneficial.

November 2022

DyaconLive and DyaconLivePlus will be activated.

Weather stations with cell phone service purchased through Dyacon will move to DyaconLivePlus.

Weather stations that upload to DyaconLive through secondary methods AND that have only one user, will be moved to DyaconLive (Basic). This category represents most users.

Stations using secondary upload methods that have more than one user will be handled individually. The administrators will be contacted and given the option.

January 2023

Annual billing will differentiate the three options

1- Cell phone with basic DyaconLive $23/mo

2- Cell phone with DyaconLivePlus at $25/mo

3- Secondary upload with DyaconLivePlus at $7/mo.

Previous users that were billed for cell phone service and data forwarding will be converted to the DyaconLive+ service, reducing their total cost.

February 2023

Final account configuration for DyaconLive and DyaconLivePlus users.

March 2023

Addition of open-water evaporation report. (Affecting DyaconLivePlus)

May 2023

Implementation of Data Retention and Data Resolution limits. (Affecting only DyaconLive basic users.)


Segmenting the DyaconLive weather station web portal will take some time. We appreciate your patience as we update the site and related information. We will try to make the transition as seamless as possible and maximize the value for all parties.

If you encounter any issues or have any feedback, please contact me.

Ultrasonic Anemometer

UA-1 Ultrasonic Anemometer

By Blog No Comments

Ultrasonic Wind Sensor, FrontDyacon UA-1 is a professional ultrasonic anemometer is now available for new weather stations and for swapping with existing weather stations. We are excited about this new product and its benefits for users.

Both UA-1 and the WSD-1 have unique characteristics that users should evaluate for their circumstances. General differences between the measurement technologies are discussed in an earlier article which you might find interesting, 3-Cup vs. Propeller vs. Ultrasonic – Which Wind Sensor is Right for You?

Advantages of Ultrasonic Anemometers

Ultrasonic anemometers are prized for their mechanical simplicity. Since they have no moving parts they can be completely sealed, protecting them from water and dust.

In the case of UA-1 the electronics are fully potted (encapsulated with epoxy). This doesn’t necessarily mean it is waterproof, but it should be at least keep the rain out and protect the electronics from condensation.

Ultrasonic Anemometer Considerations

While the technology is fascinating, there are a couple of downsides. The lack of moving parts may make UA-1 susceptible to contamination by birds and insects. So, depending on your environment, it will still need routine inspection and cleaning.

The other issue is the operating temperature. The speed of sound changes with air temperature. Ultrasonic anemometers must adjust for this in order to calculate the correct wind speed. UA-1 is specified to operate down to -15°C (5°F), which is quite cold but may not be sufficient for some environments. Keep in mind that UA-1 won’t break below those temperatures, but the wind speed may not be correct.

UA-1 Convenient Features

Ultrasonic Anemometer North Alignment

UA-1 is directly replaceable with Dyacon WSD-1. Any user wishing to swap sensors, just needs to unplug the 3-cup sensor and plug in UA-1. Of course, you still have to align north.

We have a designed the UA-1 mounting system so that it slips over the end of a 3/4″ pipe. The mounting adapter includes a compartment with a pluggable terminal block connector. This can be disconnected to removed UA-1 from an installation without pulling the full ca

ble length. It also makes the cable field replaceable.

One other convenient little feature in UA-1 is the north alignment hole. Temporarily inserting a straw or stick into the hole helps users orient the north position.

UA-1 is a great little sensor for those needed and professional ultrasonic anemometer. Please call us with any questions.

Choosing the Best Anemometer Type

3-Cup vs. Propeller vs. Ultrasonic – Which Wind Sensor is Right for You?

By: Hailey and Eugene

Date: 5/27/22

There is a wide variety of methods and instruments available for measuring wind speed and direction, so it can be overwhelming when deciding which one is right for your application. For meteorological applications, there are three basic types: 3-cup, helical, and ultrasonic.

3-Cup Anemometer

A cup anemometer is the most common anemometer on the market. The iconic design usually consists of 3 small cups that are connected to a central axis. 3-cup anemometers measure wind speed by the speed of the rotating cups. They are typically less responsive to rapid changes in wind speed when compared to ultrasonic devices; this can be good or bad, depending on the application and the characteristics of the instruments. For general meteorological use, 3-cup wind sensors mechanically provide accurate wind speed measurements.

The design is inherently omni-directional. This means they respond well to rapid changes in wind direction.

Due to their mechanical simplicity, these 3-cup designs can be very rugged. They are also simple to use and easy to troubleshoot.

3-cup anemometers are typically electrically passive, using a reed switch to indicate anemometer rotation. The speed calculation burden falls to the attached digital device. If properly designed, 3-cup anemometers can contribute to a very low-power system.

Freezing can be a problem for any anemometer. When evaluating 3-cup anemometers and vanes, look for wide drip skirts to shed precipitation. These reduce the potential for freezing. Anemometer and wind vane designs should avoid horizontal surfaces that can accumulate snow and allow water to puddle and freeze.

Wind Vanes

A wind vane for reading wind direction may be integrated with the 3-cup anemometer.

The vane orientation is typically indicated with a potentiometer, a device that changes electrical resistance when the shaft rotates a wiper on a resistance band. High-end devices will use a wire-wound resistor and metalic contact surfaces. Low-cost solutions will use a simple carbon-film potentiometer, which will have a lower operating life. Both potentiometers will have a 2 to 5 degree dead-spot where the wiper transitions from the maximum resistance to the minimum. This dead spot requires that the whole sensor be mechanically oriented for the dead spot to serve as “north.”

Propeller (or Helical) Anemometer

Propeller (or helical) anemometers look like wingless airplanes, with a propeller on the front and a rudder in back. The structure combines both wind speed and wind direction in one device. Electrically, these can be very similar to the 3-cup anemometers; wind direction is detected with a potentiometer and wind speed by a reed switch pulse. Some anemometers will use an inductive coil, resulting in a sine wave frequency that corresponds to wind speed. The circuitry to read the frequency output is more complex and more costly that a reed switch system.

Helical designs are unidirectional, which means the anemometer must rotate into the direction of the wind in order to measure the wind speed. Typically, this is not detrimental to wind measurements, but may be something to take into consideration for some cases.

Ultrasonic Anemometer

Ultrasonic Wind Sensor, FrontUltrasonic anemometers are unique in that they measure wind speed and direction with ultrasonic pulses. Because they don’t have any moving components, ultrasonic wind speed and direction sensors can be more durable, and may take less effort to maintain compared to standard 3-cup sensors. They can be deployed in harsh environments or extreme weather conditions, where anemometers with moving mechanical components are more likely to be at risk for breakage, degradation, or corrosion. However, the lack of moving parts also presents a vulnerability to insect and bird contamination. Some ultrasonic anemometers can also be affected by rain, which may temporarily contaminate the reflective surfaces. Ultrasonic anemometers are also affected by both low and high wind speeds, which may give erratic readings.

Temperature changes affect the speed of sound through air. Consequently, an ultrasonic anemometer needs to actively compensate for ambient temperature. This may complicate or reduce the environmental operating window of the instrument.

Depending on the sample rate, ultrasonic anemometers can be more receptive to quick changes in wind speed and direction. At high sample rates, the ultrasonic technology can be reliably responsive to wind turbulence. However, ultrasonic wind sensors may have a lower max wind speed than an equivalently priced mechanical. Wind turbulence through the sensor, sample rate, blowing precipitation, low transducer output, and other issues will create a technical imitation to the measurable wind speed.

All of the above issues are technical hurdles, but they combine to increase the electrical complexity, cost, and power budget of ultrasonic wind sensors.

Unlike the previous two anemometer technologies, ultrasonic wind sensors are active devices, requiring power to detect wind. Higher sample rates will require more power. While 30 to 60 mA may not seem like much, over time it can significantly add to the system cost, especially for autonomous systems. Some devices also have internal heaters, which are power hungry. Higher power budget adds to battery cost, solar power cost, shipping cost, and ongoing maintenance costs.

Dyacon Wind Sensors

Dyacon WSD-1 wind speed and direction sensor

Dyacon WSD-1 (and WSD-2) are 3-cup anemometers with integrated wind vanes. These are smart devices, incorporating digital circuitry in the anemometer itself. This allows for a high-degree of power optimization and multi-value output.

WSD-1 uses a Modbus RTU slave interface, and WSD-2 is an SDI-12 sensor.

WSD-1 is ideally suited for industrial applications and is used for Dyacon’s MS-100 series weather stations. The integrated electronics provide not only current wind speed measurement, but also 2 minute average, 10 minute average, and real-time gust capture. This reduces the burden in the host device, which would typically require significantly more power to calculate the same values. When our wind speed and direction sensor is used with automation systems, such as PLCs, the digital output and calculated values can reduce programming on the host device.

WSD-1 and -2 have proven track records with successful multi-year use in mountainous and desert environments with minimal maintenance. The service interval is 3 to 5 years, at which point Dyacon will change the bearings, update the firmware, and perform any other service for a 1 year warranty.

WSD-1 power draw is only about 2 mA, substantially less than ultrasonic sensors and other anemometers with on-board measurement processing.

Another differentiator for Dyacon WSD-1 and -2 is the wind vane uses a contactless vane sensor. As such, there is no dead spot. This allows the wind sensor to be electronically zeroed and eliminates a wear component.

We are also working on some new and exciting stuff that will serve the needs of our commercial and industrial clients. So, keep your eyes on our announcements.

If you have any questions or need further assistance deciding which wind sensor is right for your application, we are happy to help.

Rural Airport Weather Station

AWOS, ASOS, and Advisory Weather Stations

By Aviation, Blog No Comments

Often a representative of an airstrip will call us asking for an AWOS. This often leads to a discussion of their expectations, needs, and budget.


Generic terms often become associated with specific applications, AWOS is one such term. (It is typically pronounced as ay-woss, as in “Hey, toss me that wrench.” Or, “Hey, boss, how about giving me the day off?”)

The full AWOS name (automated weather observation system) sounds generic, but typically implies a class of weather station designated for aviation weather. To confuse things, ASOS (automated surface observing system) is also thrown around in a similar aviation context.

The functional differences are often of minimal importance to the aviation community, but AWOS is typically an FAA-certified weather station under the control of state, local, or private entities. The system is specifically installed and intended for aviation activities.

ASOS equipment is a cooperative effort involving the National Weather Service, FAA, and Department of Defense in the US. Like AWOS, the systems are designed specifically to serve the needs of aviation operations.

Both AWOS and ASOS systems imply a particular set of instruments. AWOS systems can be classified from AWOS I (one) to AWOS IV (four) Z/R. Each system incrementally adds more instruments. AWOS I starts with wind, pressure, temperature, and humidity instruments. Visibility, cloud ceiling, precipitation type, lightning, freezing rain, and runway condition sensors are added with each variant.

Not only is the initial cost of AWOS systems quite high, they must also be maintained by specially trained technicians in order to retain the certification. Due to their complexity and liability, maintenance requires special training anyway. Nevertheless, the total cost is often prohibitive to small airports, fly-in communities, and private operators, even when offset with government grant money.

Small Airports

So, what are small aviation users to do?

Most pilots are familiar with a plethora of aviation tools that run on Apple iPads (which seems to be the brand of choice). These planning and mapping tools often include weather data from AWOS or ASOS sources. Consequently, pilots have an expectation of the range of instrument data these certified systems provide.

However, these iPad tools are often issued under the “Advisory” umbrella, as well as many other instruments that private pilots add to their panel.

The advisory classification allows community airports, fly-in communities, and clubs to employ weather stations for their users. These could be $50 department store instruments or more expensive equipment like Dyacon MS-130.

The challenge is getting the information that you need, when you need it, and within the budget available.


Dyacon’s weather stations provide a range of capabilities that have the potential to improve aviation safety. First, Dyacon weather stations can be installed, configured, and maintained by local pilots or technicians, no special skills are required. This reduces the total cost of ownership.

Unlike the disposable consumer-grade weather stations, Dyacon stations are modular and repairable.

Aviation weather station SMS text message.

METAR and Plain Language Text Messages

Weather data can be accessed in several ways:

  • SMS text message (METAR and plain-language formats)

  • Web portal (over cell phone or Wi-Fi)

  • Cable connection to PC (which can also upload to the web portal)

    Aviation Console for Preston, ID (U10) Weather Station

    Aviation Weather Console for Preston, ID (U10)

Both the DyaconLive web portal and SMS text messages provide density altitude, altimeter, and estimated cloud base.

DyaconLive includes both current and historic information as well as NWS forecast information. The charted data helps pilots evaluate on-site weather trends. The web pages are accessible as a simplified public view or can be kept private for specific users.

The DyaconLive aviation console consolidates the critical aviation weather parameters on a single page, which is useful in flight planning rooms for pilots or in waiting areas for guests.

Big-Weather Company Tries to Make Small Station

By Blog No Comments

Afternoon (UTC) Presentation 

I came into the office one morning at 0730 hrs (1430 UTC) to sit through a presentation by a big-business weather equipment company. They invited me to a sales pitch for a new product that has not yet been released. (I always find it frustrating when a company tries to sell something that isn’t available.)

Nevertheless, the presentation was interesting and their marketing department created a highly-produced video that employed all of the popular buzz words like “micro-climate,” “future-proof,” “cyberattack,” “cloud computing,” and “IoT.”

Big-Weather’s Small Features

This new cost-optimized, professional weather station from Big-Weather is targeted to commercial users that only need one or two weather stations, want something easy to use, and don’t want to spend $10,000 USD. The basic weather data is automatically sent to their cloud service over a cell phone connection. The end solution is as plug-n-play as you can get in something that doesn’t come from a big-box store.

The system includes an integrated weather sensor suite that provides basic measurements of wind, temp, hum, precip, and pressure. This is accompanied by a solar panel, electronic control box, and separate cell phone box. The system does not have any configurable settings, no sensor options, no measurement interval option, no data cable connection, and no wireless communication options.

One interesting design choice was the system has only one day of autonomous power from the internal lead-acid battery. And, like the other features, there is no battery expansion option. But, should you need to run the weather station longer than one day without solar input, you can supply it with external power from an AC mains source.

How Much?

By the end of such a fancy presentation you might be asking: “What’s the price for this easy-to-use, no options system?”

And: “Do all of the sales reps have European accents?”

To get answers to those questions, you have to call your Big-Weather representative (because the price is a secret). You will also be informed that the system is not available until March 2021.

A Better Alternative from Dyacon

I apologize if I am being a little pithy and sarcastic, but us little guys have to make the best of what we are given and Big-Weather’s new product is an interesting benchmark. I am guessing that this new product was in development before the demise of Campbell Scientific’s WeatherHawk product line. Maybe now there’s a market gap.

Whether from Campbell Scientific or a European company, these easy-to-use systems made by big weather companies often bear the cost burden of their legacy products. These simplified products are also intentionally limited in features so as not to compete with the high-end systems from the same organizations. Fortunately, this leaves ample opportunity for Dyacon … and our customers.

So, if you want

  • Basic weather station and the ability to add other sensors,

  • Real-time wind gust capture,

  • Calculated values, such as dew point, 2 and 10 min wind averages, heat index, and so forth,

  • Autonomous operation of one week and the option to expand the battery and solar capacity,

  • DyaconLive web portal with user access control, optional public visibility, report generation, alerts, and maintenance management features,

  • Configurable local logging intervals from 1 to 60 min and DyaconLive upload intervals of 1 to 60 min,

  • Cell phone that allows users to install their own SIM,

  • Wi-Fi alternative to cell phone,

  • Modbus RTU port for cable connections to an external computer, PLC, BAS, SCADA, or other automation equipment,

  • Windows PC software for local weather display,

  • Aviation-specific features such as density altitude, estimated cloud base, two aviation web portal options, and redundant cable connection,

  • Sales and support direct from the manufacturer,

  • .. and more,

      you should probably chose a Dyacon weather station.

Dyacon Invitation

We like to be open with our customers, providing the information that professional users need to make an decision efficiently. To this end, our prices, manuals, videos, and configuration software are all on our website. You can also give us a call to discuss your needs. There is no screening, not tiered support plans, no exclusive dealer territories, and no European accent.

Dyacon may not be the oldest or biggest weather instrument company and we rarely wear white lab coats, but we do make one of the best professional weather stations for commercial, industrial, agricultural, and aviation users. And, yes, we also sell equipment to “research” users.

If you need a network of weather stations or just one, please check out our products. I think you will find Dyacon to be a compelling alternative that is available now.


Weather Hawk Station

WeatherHawk Alternative

By Blog No Comments

A Little History

Many readers will be familiar with the work and anxiety that goes into starting and operating a small business, especially a bootstrap operation funded through the skills, blood, sweat, and tears of the founders. When I hear of a business failure, I have some idea of the turmoil, heartache, and disappointment of the owners. I’ve been there. It is emotionally wrenching to walk away from a business. (Don’t worry. Thanks to some hard lessons from previous ventures, Dyacon is on a good course.)

While well-funded businesses may not leave the same wake of personal wreckage of a small business, there is still a toll to the employees when they are “restructured.”

Campbell Scientific, “world renowned” for their environmental data loggers, is located just down the street from Dyacon. In an effort to attack a broader market, Campbell Scientific (CSI) created a division called WeatherHawk. Their 900 series weather stations enjoyed good representation as a component of high-end home automation systems and similar applications. And then, Control4 realized that they could pull weather adequate data from “the internet” for free (<sarcasm>Because everyone knows that the internet is where good local weather data is found. Just ask Google.</sarcasm>).

In addition to integrated weather platforms, WeatherHawk also contracted with offshore manufacturers to create a line of handheld weather instruments, which is a very competitive market.

In spite of the challenges, CSI is a patient company and does not pull the plug on ventures until they’ve done everything they can to see them through. While I don’t know all of the reasons for the business decision, WeatherHawk has been effectively closed. Quoting from their website: “WeatherHawk has been absorbed into the regular operations of Campbell Scientific Inc.” And, as of 31 May 2020, “All other operations [have ceased].”

I was sorry to hear the news.

Early on when we were just developing our weather instruments, a salesman from Met One said the weather business was very incestuous. Indeed, there is a lot of overlap in the weather station business with one company selling a competitors products in order to meet the unique needs the end user.

While WeatherHawk 900 weather stations had slight overlap with Dyacon, our business strategies were significantly different. Dyacon has been very focused on developing our own instruments and web portal for aviation, commercial, and industrial users. Whereas, WeatherHawk was mostly focused on prosumers.

Note: If any of my friends at CSI wish to correct the above, please drop me a note.

Where Should WeatherHawk Users Go?

While exhibiting at the Great Alaska Aviation Gathering in 2019, we encountered an aviation company that was using a WeatherHawk 900 system for critical flight operations. They had contracted with another company to develop some customized charts to augment the WeatherHawk, but the system was aging and a new one was needed.

WeatherHawk Charts

Of course, I wouldn’t be writing this article if they had selected Davis Instruments or some other system.

Dyacon now provides this flight services company with an internet-connected weather station accessible through DyaconLive. The end solution is far simpler than the multi-tiered system that was previously required to connect the WeatherHawk to Ethernet, send the data to a server, convert the data to a jpg image, and display it on a computer. In spite of the hurdles, these charts were critical to providing an intuitive indication of the flight conditions for the pilots operating in a dangerous, turbulent location.

Based on user feedback, DyaconLive Aviation Console provides pilots with real-time, advisory surface weather data. The DyaconLive web portal allows pilots, flight managers, and staff to check conditions remotely, whether in Anchorage or Nanwalek. While an AWOS may be ideal, they are far too expensive and complex to serve the needs of most air ports and back-country landing strips.

If you are looking for an alternative, upgrade, or replacement for a WeatherHawk station, please keep Dyacon in mind. We design and manufacture most of our own equipment and web portal; giving us the capability to offer a level of service that most companies can’t, including a ground-up design for your network needs (which is a story for another time).


Maintenance Management System

By Blog No Comments

Maintenance Management SystemJust like any other piece of equipment exposed to the elements, weather stations need occasional service. For a hobbyist, weather station maintenance is not a problem: one station, one user. However, for professional users, maintenance tasks compete for time and resources. Staff changes can also cause a loss of continuity of knowledge.

The Book

Weather Station Service Log Notebook

A weather station site maintenance log is often used by weather station technicians. A notebook may be used to manually record equipment deployed, site visits, sensor service, and configuration changes. This information helps with data quality control. Disruptions or step-changes to senor readings can be correlated to service activities.

(Of course, the notebook is only as usable if others can decipher the handwriting.)

Maintenance Management System

As of 13 May 2020, DyaconLive now includes a maintenance log system. We have retroactively recorded the weather station equipment at current customer sites. Those customers with multiple sites, may need to adjust their equipment records.

The maintenance management system allows technicians to enter their own service schedule for the various sensors. Notifications are visible at the top of the Status page. Activities can be recorded on a data entry form. Site equipment is tracked in a table at the bottom.

Of course, any record is only as good as what you feed it. Information can be entered from your computer or handheld device. We have tried to make MMS as usable as possible and will continue to build on this feature.

In the end, a little routine attention will ensure a reliable meteorological station and a long service life.


Hurricane Test #1 – The Dorian Job

By Blog, Uncategorized No Comments

Wind tunnel testing has its place, but the real-world can be a bit rougher, like hurricane Dorian rougher. Well, maybe that sound a little hyperbolic, but 84 mph wind is still quite a bit.

Our customer reported: “The two Dyacon met stations we currently have running made it unscathed through Hurricane Dorian that just hit us. Max recorded gust from the Dyacon stations was 37.4 m/s (84 mph). . . . Not sure if this is the first CAT 1 hurricane the sensors have been through, but thought you may be interested to know.”

Dyacon sensors have been tested beyond 84 mph on a mobile platform, but this was the first time we have seen this speed in the wild as part of a full weather station.

The map shows the location of the weather station in North Carolina.

USACE Station Map

The charts below are from DyaconLive. The peak gust measured was 37.4 m/s (83.7 mph). The maximum 10 min average at the same point was 26.9 m/s (60.2 mph).
