DHT22 Temperature Sensor

DHT22 Sensor is a premium quality Humidity & Temperature Sensor from Techtonics. Moglix is a well-known e-commerce platform for a qualitative range of Humidity & Temperature sensors. All DHT22 sensors, TECH1120 are manufactured by using quality-assured material and advanced techniques, which make them up to the standard in this highly challenging field.

DHT22/AM2302 Digital Temperature & 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).

It’s fairly simple to use but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so sensor readings can be up to 2 seconds old. Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin, and the rightmost pin to the ground. Although it uses a single wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin.
