DHT11 digital temperature and humidity sensor is a digital signal output with a calibrated temperature and humidity combined sensor. It uses a dedicated digital modules and acquisition of temperature and humidity sensor technology to ensure that products with high reliability and excellent long term stability. Sensor consists of a resistive element and a sense of wet NTC temperature measurement devices, and with a high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, fast response, anti-interference ability, high cost and other advantages. Each DHT11 sensors are extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the OTP program memory, internal sensor, signal processing in the detection process to call these calibration coefficients. Single-wire serial interface, allowing the system to become simpler and quicker integration. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it a wide range of applications and even the most demanding applications is the best choice. Product is 4-pin single-row pin package. Easy connection, special packages can be provided according to user needs.
