This Si7021 sensor is specially designed for the Sonoff TH10 and TH16. With the plug the sensor can easily be connected to the Sonoff, whereby a system can now be switched on the basis of temperature and / or air humidity.
QStefanIs it true that it is based on the Si7021 chip? So the plug has 4 wires? I want to use it instead of the Adafruit plate Si7021, because it is already in a housing.ViewHide 1 answer | Answer this question
