All DHT22/AM2302 Digital Temperature & Humidity Measurement Sensor, TECH1120 are manufactured by using quality assured material and advanced techniques, which make them reliable even in this highly challenging field. Because this temp and humidity sensor delivers calibrated digital output, it is suitable for long-term data logging and indoor or outdoor environment monitoring.
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). In many compact embedded designs it effectively serves as a stable digital temperature meter for microcontrollers and single-board computers.
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. Thanks to this predictable timing, the dht22 temp humidity sensor also works reliably with microcontrollers, single-board computers and dht22 raspberry pi examples used in tutorials.
