Temperature and Humidity sensor module - DHT22 bluetooth smart The pin of VDD isDHT22 digital sensor for detecting the temperature and humidity in the environment. Unlike his predecessor DHT11, it has a high level of measuring accuracy and can be used on the street. The sensor can measure temperature from 40C to 80C and humidity from 0% to 100% with an accuracy of 1C and 1%. So if you are looking to measure in this range then this sensor might be the right choice for you. The output of a digital composite signal from the
