Upgrade to the SHT35

Posted on February 8, 2021February 8, 2021 by meteodrenthe

Around New Year’s I took the time to finally bring a new Sensirion SHT35 temp/hygro sensor online. It’s an upgrade compared to the SHT31 sensor chip Davis uses for their Vantage Pro 2. On top of it being more precise (+/- 0,1 C in stead of 0,3 for the SHT31) it also registers an extra…

Proof of concept custom console display

Posted on December 15, 2020December 15, 2020 by meteodrenthe

The Davis Vantage Pro 2 display is quite a bulky thing. I’ve added non-Davis sensors to my setup, and included a Davis AirLink in October too, which is WiFi based and not visible on the console. Plus, my console has been partially broken for a while. 🙂 Reason enough to look at an interesting alternative:…

Switch to the BMP280 pressure sensor

Posted on December 10, 2020 by meteodrenthe

In a previous post I wrote about tests of the BMP180 pressure sensor. These were not all I hoped for, so I ordered a BMP280 sensor, which is supposedly an upgrade of the BMP180. Perhaps it would give me better results. As it turns out, it appears it does! I only ordered one sensor at…

The BMP180 barometer

Posted on November 20, 2020February 17, 2021 by meteodrenthe

I have long been unhappy with the performance of the Meteostick internal barometer. Although the values it emits are usually totally acceptable, it tends to spike inexplicably multiple times a day. So, this week I finally came around to installing a new sensor, the Bosch BMP180. Its performance compared to the Meteostick can already be…

Filtering and sorting images passed to FFmpeg

Posted on November 9, 2020November 9, 2020 by meteodrenthe

My Foscam FI9900P IP-camera does not offer an option to only upload images to my server when it’s light out. Additionally, it does not create a directory for each date. Hence, I end up with a directory full of useless images made during the night that also grows enormously over time. In my previous post,…

Converting weather cam images to video with FFmpeg

Posted on November 1, 2020 by meteodrenthe

As of November 2020, I use a Foscam FI9900P as a weather cam. It is configured to upload an image twice a minute to my server over FTP. The latest image is then made available on https://meteodrenthe.nl/#/weercam. The static image is fine, but I also want to be able to show a time lapse, a…

My Pi Zero + Meteostick setup

Posted on October 31, 2020July 27, 2022 by meteodrenthe

I have been using the Meteostick in combination with a Raspberry Pi to process sensor updates from the Davis Vantage Pro 2 setup for about 10 months now. The setup has undergone some changes. Currently, I have the Meteostick connected to a Raspberry Pi Zero W. This has a singular responsibility: read the updates from…

Reading the Meteostick from the Linux terminal

Posted on October 31, 2020July 27, 2022 by meteodrenthe

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…

The purpose of this blog

Posted on October 30, 2020September 7, 2022 by meteodrenthe

I’ve owned a weather station for several years. Back in 2016, I started out with a Oregon Scientific WMR200. This wasn’t simply a station with a console. Right from the start, for example, I began playing around with an Rfxcom transceiver to process the data transmitted by the sensors on the 433 Mhz frequency. For…
