Product Description

This module integrates DHT22 (or AM2302) sensor and other required components on a small PCB.  The DHT22 sensor includes a resistive-type humidity measurement component, an NTC temperature measurement component and a high-performance 8-bit microcontroller inside, and provides calibrated digital signal output.  It has high reliability and excellent long-term stability, thanks to the exclusive digital signal acquisition technique and temperature & humidity sensing technology.

DHT22 is a upgraded version of DHT11, and provides better resolution and accuracy. The only drawback, comparing to DHT11, is that its maximum sampling rate is even lower: with DHT11 you could request data for every one second, but with DHT22, you could request data for every two seconds.

Technical Specifications:

Power Supply: 3.3~5.5V DC
IO level: 3.3~5.5V (depends on power supply)
Power Consumption: 2.5mA max while requesting data
Measurement Range: Humidity 0-100%RH, temperature  -40~80℃
Accuracy: Humidity ±2~5%RH, temperature ±0.5℃
Resolution: Humidity  0.1%RH, temperature  0.1℃
Sampling Rate: No more than 0.5 Hz (once every 2 seconds)
Long-Term Stability: <±0.5%RH/year

Additional Information

Weight 0.01 kg
Dimensions 3.2 x 1.6 x 0.9 cm

    Using the sample code available on this website it was possible to setup the sensor module with a Pi in a matter of about ten minutes. It is really awesome to get working results this fast. Shipping to Germany took just a few days which was great as well.
