The Davis Instruments solar radiation and UV sensors require a specific mounting plate. As far as I’m aware, there are two options available. You have the sensor mounting shelf which can be attached to the rain collector. Then you have this universal mounting bracket. It can fit one radiation sensor. It also comes with the […]

Good barometers: the BMP388 and BMP390
Barometric pressure is considered to be one of the less interesting metrics to measure with a personal weather station. As a factor in global weather predictions it is very important, but in terms of current conditions we learn a lot more from our thermometers, anemometers, rain gauges and other sensors. Especially if we are considering […]
Trying out a Vaisala DTR504
I’ve pretty much settled on my current radiation shield setup. Based on personal research alongside that of others, I do not think I will find an affordable radiation shield that can outperform the Barani MeteoShield Pro. Whenever I have doubts about radiation errors, the results produced by sensors inside my actively ventilated Apogee TS-100 will […]
Temperature sensor responsiveness
The passing of a sharp weather front, accompanied by a sudden increase or decrease in temperature, is a good occasion to analyze temperature sensor behavior. Especially apparent becomes the responsiveness of different sensors. February 4th 2022 didn’t see any spectacular weather, but during the afternoon a cold front passed over which caused a very abrupt […]
Apogee TS-100 first impressions
I was losing the last light and had to get a flash light while connecting the last wires Tuesday evening (August 17th), but I have the TS-100 up and running. Without battery backup for now. I will fix that later. Adding this new shield to my setup has triggered a whole series of new tests […]
Monitoring radiation shield performance
Spring is here. Today was the first ‘warm’ day (> 20°C) of the year. Conditions where solar radiation errors will start cropping up in the temperature data. Accuracy of temperature readings is a surprisingly complex subject. But any attempt to get accurate readings starts with shielding the sensor from direct or indirect sunlight and ensuring […]
WeatherLink Live, local API and barometer
A few weeks ago, I made the switch from reading my Davis sensors with the Meteostick to the Davis made WeatherLink Live. Though I still like the concept of the Meteostick, the reception is fairly poor and sometimes it would stop receiving data and require a reboot. One thing you don’t have with the WeatherLink, […]
Reading the Meteostick from the Linux terminal
Recently I obtained several Davis Vantage Pro 2 components. Since I’m not interested in using the Davis console, but want to write sensor readings directly to a database, I looked into the Meteostick. Even though the Meteostick costs around 160 euros, it is still a relatively cheap way to access the readings from Davis sensors. There […]
