Description DHT22 Temperature and humidity sensor

The AM2302 DHT22 is a digital temperature and humidity sensor module. It uses a capacitive humidity sensor and a thermistor. This allows the ambient air to be measured.
The sensors are easy to use. The only disadvantage of this sensor is that a measurement can only be taken once every 2 seconds.

    it works but is a bit sensitive, have one in my palludarium where there is a very high humidity so that it sticks, so to speak, have now ordered 2 if this happens again i will exchange them so that the one that comes out and is stuck working again for a few days in a dry place
