The AM2302 (Wired DHT22) Temperature and Humidity Sensor is a cost-effective digital sensor. DHT22 AM2302 Sensor Module Without Board design is also simple and easy to use. This DHT22 sensor uses a capacitive humidity sensor and thermistor. With the help of a thermistor and humidity sensor we can measure ambient air. After measure the ambient air it outputs a digital signal on the data pin. For this Am2022 no analog input pins required. This sensor is a wired version of DHT22 and it contains a large plastic body. This sensor is basic and simple. It is also a low-cost digital temperature and humidity sensor. Get all types of temperature and humidity sensor at epro.pk.
