Overview


DHT22 is a high-performance temperature and humidity sensor, ensuring high reliability and excellent stability.

It uses a capacitive humidity sensor to measure the relative humidity and a negative temperature coefficient thermistor (NTC) to measure the temperature. Those sensing elements are pre-calibrated and the output is provided as a digital signal. Data can be read once every 2 seconds.


Specifications

  • Operating Voltage: 3.3 V to 5 V
  • Current: 2.5 mA
  • Humidity sensing range: 0 to 100% RH
  • Humidity measurement accuracy: 2 to 5% RH
  • Temperature measurement range: -40 °C to 80 °C
  • Temperature measurement accuracy: ±0.5 °C
  • Response time: 2 seconds
  • Dimensions: 27 x 59 x 13.5 mm

Works fine

Bought it to experiment with ESP8266 home automation. Got it working in about 10 minutes. Shows same reading as my home thermostat.

    Great upgrade to the DHT11

    I was using DHT11 modules previously, and then i figured i would try the DHT22's. i like the DHT22's better. they seems a little more accurate, and some issues with the DHT11's have been corrected.

      Gets the job done.

      Accurate sensor works with Raspberry Pi given the right drivers
