DHT22 Temperature and Humidity Sensor Module

DHT22 (AM2302) – Humidity and Temperature Sensor is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.

Features:

  • 3.3-5V Input
  • 1-1.5mA measuring current
  • 40-50 uA standby current
  • Humidity from 0-100% RH
  • -20 – 80 degrees C temperature range
  • +-2% RH accuracy
  • +-0.5 degrees C
  • Pin Mapping (When the Sensor is kept facing you, left most pin is Pin 1)
  • VDD power supply (3.5-5.5V)
  • SDA serial data – bidirectional
  • NC NC
  • GND

Pin Identification:

No: Pin Name Description
For DHT22 Sensor
1 Vcc Power supply 3.5V to 5.5V
2 Data Outputs both Temperature and Humidity through serial Data
3 NC No Connection and hence not used
4 Ground Connected to the ground of the circuit
For DHT22 Module
1 Vcc Power supply 3.5V to 5.5V
2 Data Outputs both Temperature and Humidity through serial Data
3 Ground Connected to the ground of the circuit
