AM2302 Temperature/Humidity Sensor



The AM2302 is a great weather sensor package. This uses 1 digital input to the microcontroller and provides temperature accurate to +/- 0.5°C and humidity accurate to +/- 2% relative humidity. The sensor will operate on 3 to 5VDC and its logic level output will be the same as the input voltage.

The sensor has a built in 5.1K resistor so no additional pull up resistor is required with this model.


  • 3 to 5V power and I/O
  • 0-100% humidity readings with 2-5% accuracy
  • 0.5 Hz sampling rate
  • 2.5mA max current use during conversion
  • -40 to 80°C temperature readings ±0.5°C accuracy
  • Body size 27mm x 59mm x 13.5mm
