DHT22 Digital Temperature and Humidity Sensor

Regular price R 90.00
  • For improved temperature and humidity measurement requirements, this DHT22 is what you want.
  • The name for the DHT22 when in this package shape, is the AM2302.
  • Good for 0-100% humidity readings with 2-5% accuracy
  • Good for -40 to 80°C temperature readings ±0.5°C accuracy
  • Can poll every 2 seconds

  • Link to Datasheet
  • Link to Arduino DHTxx Library
  • Link to another Arduino Playground Library
  • Link to the Adafruit Library
  • Link to Example circuit
  • Example
  • (Image source website)
    • From your microcontroller:
    • 5V to 1
    • Data pin to 2
    • GND to GND
  •  Then download the DHT library from Adafruit
  • https://github.com/adafruit/DHT-sensor-library
  • and read from the data pin with 
  •    hum = dht.readHumidity();
  •     temp= dht.readTemperature();
