Hello friends, I hope you are all fine and will be doing something interesting in your life. in today's post, I am going to discuss Introduction to DHT22 . It is a temperature and humidity measure sensing device. It is easily used but it needs a specific time for an operation. Its temperature measuring range is from -40 to +125 degrees Celsius with +-0.5 accuracy. This sensor measures moisture content and temperature. This sensor is easily connected to other microcontrollers. DHT22 plays an important role in our environment in measuring temperature and moisture. It is a low cost easy-to-use small sensor. This sensor is used at different weather stations to measure temperature and ratio of moisture in the air, in this way, they tell about temperature or rain prediction. In today's post, I w ...
