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.
