DHT22- digital sensor for detecting the temperature and humidity in the environment. Unlike his predecessor DHT11, it has a high level of measuring accuracy and can be used on the street.
Also DHT22 have a chip inside that can store the measurements and later transfer them to the controller.
The only lack of this sensor is that the received data is delayed by 2 seconds.
Current:2.5mA max use of current during conversion (while requesting data).
Humidity:0 – 100%, ÷ 2%.
Temperature:-40C + 125C, ÷ 0.5%.
The sampling rate no more than 0.5 Hz (once every 2 seconds
