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.
