DHT11 Temperature-Humidity Sensor

DHT11 digital temperature and humidity sensor is a compound sensor with calibrated digital signal output. It use dedicated digital module acquisition technology and the temperature and humidity sensor technology, ensure that the product has a very high reliability and excellent long-term stability. Sensor consists of a resistance type moisture element and a NTC temperature measuring element, and connected to a high-performance 8-bit microcontroller. So the product has excellent quality, super fast response, strong anti-interference ability and extremely high performance-price ratio. Every DHT11 sensor in extremely precise humidity calibration laboratory calibration. Calibration factor stored in OTP memory in the form of program, the sensor need invoke these calibration coefficient in the detection model process. Single wire serial interface which make the system integration becomes simple and fast. Super small volume, low power consumption, making it to the class application the best choice for even the most demanding applications. Products for single row pin 4 needle assembly, convenient connection
