Note that on the internet there are many temperature/humidity sensor boards with I2C available. The board above mentions SI7021, SHT21 or HTU21. These are separate microchips, check what you have bought.
|
|
The SI7021 and SHT21 are **not** compatible. This plugin only supprts the SHT21, SHT20 and SHT25.
