Low-cost digital temperature and humidity sensor

16.50 AED

The DHT22 is a basic, low-cost digital temperature and humidity sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin. It requires careful timing to grab data.

Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to 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!

Note: Its needs a 4.7k~10k Pullup resistor on the data line, so make sure to use on the data line, alternatively check this DHT22 Sensor Module we have, it comes with onboard pullup and decoupling capcitor on the supply line.
