Interesting sensors for your weather station
Do you have any own weather station? 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 weather station (meteostation).
Sensor of temperature, humidity, pressure, UV, light intensity, ...

A lot sensors from the list you can use for weather station board which I designed. The weather station 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 weather station 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 weather station board.
