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 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.
Technical details:
Power supply: 3.3V.
Current: 2.5mA max use of current during conversion (while requesting data).
Humidity: 0 - 100%, ± 2%.
Temperature: -40°C + 125°C, ± 0.5%.
The sampling rate no more than 0.5 Hz (once every 2 seconds).
