PESSL INSTRUMENTS AIR TEMPERATURE AND RELATIVE HUMIDITY SENSOR

Measures air temperature and relative humidity and is used for low power consuming applications on μMETOS CLIMA (LoRaWAN^®, NB-IoT).
I2C Bus Considerations: I2C Bus is sensitive to electromagnetic waves and can be distorted under certain conditions. On the contrary, Hygroclip is less sensitive.
Recommended cable length: no longer than 1 m.
