The sensor includes aط¢آ capacitiveط¢آ 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 cost-effective.
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 importedط¢آ SHT10ط¢آ 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 sensorط¢آ Arduino expansion board,it will be easily implemented the interactive effect which related to the temperature and humidity perception.
Note:ط¢آ 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.
