DHT-11 Digital Humidity Temperature Sensor


DHT11 digital temperature and humidity sensor. It utilizes a digital serial output that returns a calibrated temperature and humidity reading. The sensor consists of a resistive element and a sense of wet NTC temperature measurement devices, and with a high-performance 8-bit microcontroller. It is a high quality, low cost sensor device. Each DHT11 sensor is accurately calibrated in a humidity calibration chamber. The calibration coefficients  stored in the OTP program memory, internal to the sensor The calibration coefficients is utilized to provide more accurate readings. Single-wire serial interface is used for simple interfacing. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it great for a wide range of applications. Product is 4-pin single-row pin package.
