The DHT22 Digital Temperature and Humidity Sensor is a low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). The DHT22 Digital Temperature and Humidity Sensor is ideal for learning, testing, and real-time monitoring projects. Its compact design and consistent performance make it suitable for students, diy makers, and automation applications.
