Temperature sensor and humidity sensor DHT22

Temperature sensor and humidity sensor DHT22

Product information:

The DHT22 is a temperature and humidity sensor in 1.
Because the DHT22 provides a digital output, it is perfect for all kinds of Arduino projects!
For example, starting a fan if a room becomes too humid or too warm.
(Google DHT22 Arduino for programming examples and libraries.)
The DHT22 is the big brother of the DHT11 and is more precise and has a greater range.

Response time: < 3 sec.

Humidity measuring range: 0-100% RH
Humidity sensitivity: +/- 2.0% RH

Temperature measuring range: -40 ~ +80 C
Temperature sensitivity: +/- 0.5 C

Connection voltage: 3.3 - 6V.
Current consumption: 0.8mA (idle) / 1.5mA (during measurement)

Dimensions: 1.5 x 2.5 x 0.7cm
