DHT22 Module

DHT22 module Digital Temperature and Humidity Sensor Module

DHT22 Module (also known by RHT03) 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. DHT22 is more accurate and has more dynamic range than DHT11 sensors.

Technical Details:

• 3.3-5.5V Input
• 1-1.5mA measuring current
• 40-50 uA standby current
• Humidity from 0-100% RH
• -40-80C Temperature Range
• +-2% RH accuracy
• +-0.5 degrees C
