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.
