Description

DHT22 capacitive
humidity sensing digital temperature and humidity module is one that
contains the compound has been calibrated digital signal output of the
temperature and humidity sensors. Application of a dedicated digital
modules collection technology and the temperature and humidity sensing
technology, to ensure that the product has high reliability and
excellent long-term stability.

The sensor includes a capacitive
sensor wet components and a high-precision temperature measurement
devices, and connected with a high-performance 8-bit microcontroller.
The product has excellent quality, fast response, strong anti-jamming
capability, and high cost.

Standard single-bus interface, system
integration quick and easy. Small size, low power consumption, signal
transmission distance up to 20 meters, making it the best choice of all
kinds of applications and even the most demanding applications.

DHT22 has higher precision and can replace the expensive imported SHT10 temperature and humidity sensor.

It
can measure the environment temperature and humidity to meet the high
demand.The product has high reliability and good stability.If it’s used
and combined with special sensor Arduino expansion board,it will be
easily implemented the interactive effect which related to the
temperature and humidity perception.

Caution: DHT22 digital
temperature and humidity sensor is designed for analog sensor
interfaces. The analog port will be used as the digital which will not
occupy the original digital port of the Arduino.The lines of the sensor
which can transform the analog function to digital that can be use on
digital port.
