DyaconLive is an ongoing project. We want your weather station to provide usable, actionable information. The Grower’s Report is a case in point.

v1.19 Summary

DyaconLive release version 1.19 on 15 July 2019 included the following improvements.

• Grower’s Report now includes an upper temperature threshold and last freeze marker.
• Charts added for new IRT-201 infrared temperature sensor.
• Sunrise/sunset added to Weather page.
• Improved screen size responsiveness for mobile devices.
• And, some back-end work, which is always going on.

By the way, Chris Cox, our staff scientist and DyaconLive developer deserves a big pat on the back for his work.

Improved Responsiveness

The navigation menu at the top of the screen should collapse into an icon on smaller screens.

Personally, I’m not a fan of the three-line, hamburger icon, it’s a bit ambiguous. But, when your computer has to fit in the palm of your hand, there isn’t much choice.

This may work better on some devices than others. Let us know what you find.

Grower Report Improvements

When setting the Grower’s Report, the upper threshold is added in a new field. For some crops, such as corn, hotter does necessarily mean more growth. The upper threshold is capped at this value. (Upper threshold is not required to generate GDD.)

This upper threshold is shown on the temperature history chart.

The Last Freeze value is shown on the GDD chart.

If you have other reports you would like to see, please let us know.

I’ve worked in cubicle environments where windows were scarce. In fact, in one job as a product design engineer, my desk was in the server closet; no windows, constant fan noise, and plenty of heat. Fortunately, I could get up a few times a day and walk outside. However, the owner’s desk was by the only entrance. So, to go outside for some light, you were advertising that you were not at your desk. And, if that wasn’t enough, he had cameras covering the whole work area so he could keep an eye on you even at your desk.

Of course, it could be worse, some people work in underground buildings; no windows and no outdoor strolls to keep one in touch with reality.

A Dyacon weather station was sold to just such a place. Not only is it underground, but there is no internet connection and no wireless was allowed. Dyacon Weather Station display software was included with the weather station purchase.

Weather Station Display is displayed on a computer monitor in break room areas, along with closed circuit camera images. The intent is to provide employees with some contact with the surface conditions.

Weather Station Display software not only meets the needs for a simple weather station interface, but also connects directly to the weather station. For security and practical reasons, wireless was not an option.

So, if you are in the dark regarding weather, Dyacon has an answer.

We are always working on one development or another, whether DyaconLive, new sensors, new [secret stuff], or expanding the capabilities of existing weather station capabilities.

Recently, we were contacted by an organization that needed a reasonable cost solution for a heat-island study. The goal was to collect baseline pavement surface temperature this year, apply new surface treatment, and then measure the difference next summer. The system had to provide real-time data to a web portal as well as local data logging.

So, we went to work; leveraging our CM-1 weather station controller and DyaconLive in order to deliver the functionality required in the short time frame.

First Test Of Infrared Thermometer

It’s always fun cobbling together the first system and giving it a spin. Often we are enamored by its inelegance. As the images attest, this is definitely not elegant. But, that comes with time. At this stage, the data is most important; and, Chris, our staff scientist, is whiz at collecting data and building scripts for analysis.

Infrared Thermometer Applications

In addition to the heat-island study at hand, there are a number of applications that we can see for this new device.

Sub-surface temperature modeling

Foliage and crop canopy temperature

Ground temperature

Road surface temperature

Race track temperature

Roof temperature

Storage tank surface temperature

Outdoor sport court temperature

I’ll leave you to come up with more applications for an infrared temperature sensor for your business. Give us a call if you want to explore anything in particular.

The measurement temperature range of this device is -20 °C to 1000°C (-4° to 1830°F), which is quite a spread. While the maximum temperature is inadequate for plasma furnaces, it is high enough to monitor your local lava flow.

Please check back later. I’ll add more to this post as we make progress toward product release in August.

Unlike large companies, Dyacon “market research” comes through customer feedback and requests. We have received several requests over the last couple of years to develop a WiFi weather station. Well, we’ve finally done it. (Yes, sometimes we are slow.)

While WiFi seems like a logical step, the implications of a short-range radio connection bring installation, data distribution, and support complications we were not ready to address at the time. Now, with DyaconLive in place, we can provide the data accessibility that users expect.

Remote WiFi

We typically think of WiFi as a short-range, local data communication mode, but with the right equipment, WiFi can cover a relatively long distance and operate in remote locations.

A property development in western Wyoming contacted us for a weather station for their private runway. While they didn’t have cell phone service in their remote mountain location, they did have HughesNet satellite Internet service. Using a 2.5 GHz outdoor access point, we achieved one mile range. This meant that the weather station could be located at mid-field by the runway.

The low data rate requirements of the Dyacon weather station means that there is no significant impact to their HughesNet account. Dyacon equipment also does not need a static IP, allowing a lower cost Hughes service plan.

Normally, our users do the equipment installation. In this case, we were contracted to do the installation (and I’m always happy to get out of the office and work in the field). Since we hadn’t previously done a connection over HughesNet, I was glad to participate in the installation.

The following are a few images from the adventure.

The flight in – 15 min by plane or 1.5 hrs by land. In this case, we flew in and drove back.

If you have similar needs for a WiFi weather station, please give us a call. We would love to see what we can do for you.

“Dust in the wind” may be a great poetic analogy for a melancholy 80’s rock song, but in reality we generally don’t like dust.

Large particles are filtered in the upper respiratory system, but the smaller the particle, the farther into the airways they penetrate.

Dust particles are measured in micrometers (μm or um), also know as microns. Particles that are 10 microns and larger are typically not detrimental to health. These would include dust, pollen, and mold spores. Of course, some materials can be dangerous regardless of size, but other particulates are dangerous because of their size. Read More

Elk: 1   Weather Station: 0

A repeat customer placed a research weather station in the field last fall. By February, anomalous readings from the weather data were observed, including a low battery alarm text message. Everything indicated that something fishy was going on – but it turned out not be be fish at all.

Since it was a relatively short 3 hr drive, I offered to make a service call to better understand the situation. Conditions couldn’t have been better for a service trip; mud, snow, rain, and cold are always a refreshing break from the comfort of the office.

After mucking through a 1/2 mile of … muck, I found the weather station torn to pieces. Read More

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. Read More
