Description
Relative humidity and temperature measurement
All calibration, digital output
Excellent long-term stability
Completely interchangeable
The Gravity DHT11 Temperature and Humidity Sensor features a calibrated digital signal output with the temperature and humidity sensor complex. Its technology ensures the high reliability and excellent long-term stability. A high-performance 8-bit microcontroller should be connected in order to get the most out of the sensor. This sensor includes a resistive element and a sense of wet NTC temperature measuring devices. It has excellent quality, fast response, anti-interference ability and high cost performance advantages.
Each DHT11 sensors features extremely accurate calibration of humidity calibration chamber. The calibration coefficients stored in the OTP program memory, internal sensors detect signals in the process, we should call these calibration coefficients. The single-wire serial interface system is integrated to become quick and easy. Small size, low power, signal transmission distance up to 20 meters, making it a variety of applications and even the most demanding applications. The product is 4-pin single row pin package. Convenient connection, special packages can be provided according to users need.
Have a newer version where they cut corners. The board was shortened and the sensor now hangs freely off the end. Disappointing for a DFRobot product. I removed the DH11 and replaced it on the backside for better support. The leads are reversed but I just rewired the connector. Works well.
