DFRobot - Gravity: DHT11 Temperature & Humidity Sensor For Arduino

DFRobot's latest generation of digital DHT11 Temperature and Humidity sensor is as powerful as it used to be but easier to use.  This  DHT11  Arduino  temperature and humidity sensor has a full range temperature compensation, low power consumption, long term stability and calibrated digital signal. A high-performance 8-bit microcontroller is integrated in the sensor with calibration-coefficient saved in OTP memory to provide accurate temperature readings.

To ease the difficulty,  a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match to connect with your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi,  intel edison, joule and curie.
