Interesting sensors for your meteostation
Do you have any own meteostation? Check this article. Here is a short list of interesting sensors.

What kind of sensor do you use? Temperature, humidity ot pressure sensor? You can improve your meteostation.
Sensor of temperature, humidity, pressure, UV, light intensity, ...

A lot sensors from the list you can use for meteostation board which I designed. The meteostation board has 4 pin headers where is connected I2C and also it has one analog input. The is step-by-step tutorial how to set the meteostation board. The board contains WiFi module, so the data is sent through WiFi or you can connect OLED to this board.
Here si the article about meteostation board.
