DHT11 digital temperature and humidity sensor is a calibrated digital signal output with the temperature and humidity combined sensor. It is application specific digital modules acquisition and temperature and humidity sensor technology, to ensure that products with high reliability and excellent long-term stability. Sensor includes a resistive element and a sense of wet NTC temperature components, and with a high-performance 8-bit microcontroller connected. So the product has excellent quality, fast response to anti-interference ability, high cost performance advantages. Each DHT11 sensors are extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the OTP program memory, internal sensor, the detection signal processing to call these calibration coefficients. Single-wire serial interface system to get quick and easy system integration. Small size, low power, signal transmission distance up to 20 meters, making it the most demanding types of a
