The DHT22 module is designed to measure the temperature and humidity of the atmosphere. The difference from the younger model (DHT11), The DHT22 has a wide range and a high precision determination of temperature and humidity. The sensor works on the OneWire bus, which makes it possible to connect it to the Arduino only three wires ( two of which are POwer supply). Low power consumption allows you to install it on stand-alone devices.
