Working of DHT sensor – DHT11 and DHT22

DHT stands for Digital Humidity and Temperature. The DHT sensor is a low-cost digital sensor for sensing temperature and humidity.  This sensor can be easily interfaced with any micro-controller such as Arduino, Raspberry Pi to measure humidity and temperature instantaneously. It can be used for a number of applications as we will see later. In … Continue reading Working of DHT sensor – DHT11 and DHT22
