DHT22 temperature and humidity sensor DHT22 is a much more accurate version of the DHT11 module popular among electronics. This device allows you to measure the temperature and humidity of the environment. Each sensor in this model is temperature compensated and calibrated in an accurate calibration chamber, making the DHT22 fit for all kinds of tough applications requiring high precision. Thanks to its popularity, the module is very easy to communicate with the Arduino environment, having at our disposal a wide range of libraries. Curiosity! Thanks to the manufacturer's own protocol, the module allows for long-distance communication. We can easily connect the sensor with a cable up to 20 meters, and some users have declared trouble-free communication up to 100 meters!
