DHT20 Temperature Humidity Sensor I2C

The Sensor DHT20 for temperature and humidity is a low-cost and easy-to-use device for measuring ambient temperature and humidity levels. It uses a capacitive ceramic humidity sensing element and a thermistor to measure the relative humidity and temperature, respectively. The sensor outputs a digital signal over I2C serial bus, making it very easy to use with microcontrollers such as an Arduino.

Aosong Sensor DHT20 is factory-calibrated and communicates with a microcontroller on its I2C bus.

Library and example code for Arduino is available.
