This measuring probe is equipped with a temperature and relative humidity sensor for air.

It can be used to measure air temperature and relative air humidity in spots that are hard to access. This probe can be connected to a Canique Climat Pro sensor or a microcontroller of your choice.

Please note: If you are using this board with your custom microcontroller. you need to add external pullup resistors for SDA + SCL. Canique senders (Climat Pro e.g.) do have them onboard.

Compatibility

Compatible with all Canique Climat Pro sensors.
