DHT11 Temperature and Humidity Sensor
INTRODUCTION
DFRobot's latest generation of digital Temperature and Humidity sensor is as powerful as it used to be but easier to use. DHT11 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.
With the new 3 pin connector that includes several soldering pads and a sturdy casing, plugging in and out the sensor is not going to be a problem anymore. The 3 pin connector is perfect to get it going fast, and extremelly easy to use with our 3 pin sockets expansion boards. Reliable and inexpensive with plenty of documentation and projects online.
