Description DHT22 Temperature and humidity sensor
The DHT22, also known as AM2302, is a reliable sensor for measuring temperature and humidity. This digital module is easy to use and fits in various applications. The sensor combines a capacitive humidity sensor with a thermistor. This duo guarantees accurate measurements of the ambient air. The DHT22 is designed for hobbyists and professionals. It is a favorite in weather stations, smart homes and agricultural projects. A small limitation is the measurement frequency. The sensor refreshes data every 2 seconds. This ensures reliable results without overloading the sensor.

Product was exactly as expected.
Rob Bontekoe (verified owner) -
It works as expected and, given previous experience, also works well on 3,3V instead of 5V.
Jos Potappel (verified owner) -
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
