Weather Station Battery Test

  • October 10, 2017

Design Principle

Most Dyacon weather stations ship with a battery and solar panel. The 12 VDC 7 Amp-hour battery sustains the weather station over night and can even run the weather station for about one week without recharging.

All Dyacon weather station controllers have an embedded solar charge controller. The internal battery recharges each day using power from the solar panel.

The daily charge-discharge cycle gradually reduces the battery capacity. Batteries that operate in cold temperature environments or are deeply discharged will suffer more capacity loss than those that operate in room temperature conditions.

Weather station batteries take a lot of abuse and should be replaced routinely for reliable operation.

Battery Testing

So, how do you know if your battery needs to be replaced?

Compare 3-cup, Helical, and Ultrasonic Anemometers

  • September 7, 2017

 

For most common meteorological variables, a variety of methods exist for measurement. Wind is no exception and given the plethora of available anemometers ranging from mechanical to ultrasonic, it can be difficult to determine which sensor is right for your application. This quick overview will give you the basics to point you in the right direction.

Dyacon Weather Stations For Drag Racing

  • July 25, 2017

In racing, there are two reasons for collecting weather data.

  • Engine performance analysis – Density altitude (DA)
  • Public safety – Lightning detection and heat index

Weather and drag racing

Density altitude is used to describe the density of the air using temperature, barometric pressure, and relative humidity. In a hot and humid location, the density altitude may be much higher than the actual altitude. Why does it matter? When the density altitude is higher than the actual altitude, engine performance may be decreased. Inversely, when DA is lower there is more oxygen available resulting in faster cars and better ET’s.

An on-site weather station can provide wind speed and wind direction measurements. These are important considerations for vehicle control during front-wheel lift and chute deployment. Wind conditions may also have an affect on ET.

Weather Station Display Solution for Local Data

  • June 9, 2017

Dyacon has provided fully autonomous weather station solutions to our commercial and industrial users for several years now. Nearly all stations have used the embedded cell phone to provide a reliable wireless interface for a Weather Underground connection, data log upload, and remote command and control.

Nevertheless, there are some applications that require a local solution or one that does not have reoccurring costs.

Dyacon Weather Station DisplayTM software fits this need.

The Best Weather Station

What is The Best Weather Station?

  • April 21, 2017

All tools are designed with particular constraints in mind. Engineers must balance design priorities such as precision, cost, ease-of-use, application needs, material characteristics, operating environment, manufacturability, serviceability, and so forth. Compact cars and 4×4 trucks are optimized for their intended application and within their own unique design constraints.

A plastic, $40 weather instrument may be just as effective for a specific application as one that costs $25,000.

3D Printed Anemometer (Wind Speed Sensor)

  • March 27, 2017

Build Your Own Anemometer?

Good anemometers can be expensive. Numerous do-it-yourself versions can be found on the Internet and are made with various components from paper cups to PVC pipe fittings. There are even some 3D printed designs that emulate molded or machined anemometers, but are typically very fragile.

The electronics for do-it-yourself weather instrument are often based on hobby boards, such as Raspberry Pi or Arduino. While function for some applications, they may not offer the robust features for commercial applications.

Weather Station Lease

  • March 24, 2017

Dyacon now offers weather station leasing and rental options for full weather stations.

Minimize Up-front Cost

The purchase cost of weather station equipment can be a barrier to new users, especially if there is some doubt over the suitability, capability, or data compatibility.

Short Term Need

Satisfy short-term needs for weather conditions, heat stress, or lightning detection. Seasonal or temporary stations provide measurement data and risk management information for sporting events, road races, wildfire support, fugitive dust monitoring, or research projects.

A leased station minimizes the long-term overhead in storing and maintaining equipment.

Setup and takedown services are also available for some locations.

Free Updates and Repairs

Repairs and updates are included in the lease cost. If a sensor fails, return it for replacement. Firmware updates are free. Battery replacement is free. Instrument service is free. Wireless cell phone service is free. On-site service contracts are also available for some locations.

Dyacon Advantage

As an equipment manufacturer, Dyacon is able to service and support leased or rented stations much more effectively than leasing companies. It’s our equipment. We built it. We know how it works. Consequently, your lease cost is lower than other sources.

Give us a call to see if a lease is right for you. Contact Us

MesoWest

  • February 27, 2017

Dyacon weather stations are now compatible with MesoWest, a weather data service developed by the University of Utah with API access through SynopticLabs.

MesoWest is a free weather data portal that is advertisement free. Data is available in graphic and tabular formats. The data may also be downloaded for further research and analysis. The SynopticLabs API allows users to create their own web portals using National Weather Service and personal weather station data.

Have You Cleaned Your Rain Gauge

  • December 17, 2016

We make most of our instruments at Dyacon but we do not make the rain gauge that we sell with Dyacon weather stations. We tested and evaluated a number of different rain gauges before selecting the Hyrdological Services (now Hyquest) rain gauges. You can see a wonderfully entertaining video here.

One of the critical, yet often overlooked, features of a rain gauge is it’s susceptibility to insect intrusion. The first rain gauge we tested turned out to be a wonderful place for insects. Below is a picture of this gauge after one year in the field.

Dirty Rain Gauge

As you can see from this image, the base plate of the gauge has several large holes (at least from the perspective of insects. While there is a stainless steel screen, a large gap remains when the top cylinder of the gauge is mounted. The cylinder also leaves a significant gap between the base plate and the cylinder.

Interestingly, this gauge uses a funnel design that is prone to clogging with dust. While it has two screens, as many gauges do, dust would filter through the screens and become impacted in the funnel nozzle.

We have used Hyquest TB-4 and TB-6 rain gauges in the field for several years. These are mid-range instruments are based on higher-end versions and quite suitable for most commercial applications.

The base has a molded vent in the base and each drain port has a molded-in screen (had to see in this image). The cylinder also overlaps the base, minimizing any gaps. (One other thing to notice on this rain gauge is the option to connect tubes to collect the rain fall and validate automatically recorded measurements.)

So, the moral of the story…

Clean your rain gauges at least twice per year (video here).

And, if you have one that collects bugs, consider replacing it.

Enjoy the weather,

Eugene
