Description

Product information "DHT22 - Digital temperature and humidity sensor"

The DHT22 is a simple, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the ambient air and outputs a digital signal on the data pins (no analogue input pins required). It is relatively simple to use, but requires careful timing to capture data. The only real disadvantage of this sensor is that you can only get new data from it every 2 seconds, so the sensor readings can be up to 2 seconds old.

Technical data
  • Operating voltage: 3 - 5V
  • 2.5mA maximum current consumption during data request
  • Measuring ranges:
    • Humidity: 0-100%, ±2-5% accuracy
    • Temperature: -40 - +80°C, ±0.5°C Accuracy
  • 0.5 Hz sampling rate (once every 2 seconds)
  • Dimensions approx. 27 x 59 x 13.5 mm
