The DHT22 AM2302 Digital Temperature & Humidity Sensor is an affordable digital sensor designed to measure temperature and humidity. It uses a capacitive humidity sensor and a thermistor to gauge the surrounding air and outputs a digital signal through the data pin, eliminating the need for analog input pins.
The sensor is relatively simple to use but requires precise timing to read the data. One limitation is that it only provides new data every 2 seconds, so readings may be up to 2 seconds old. To connect the sensor, attach the first pin on the left to a 3-5V power supply, the second pin to your data input pin, and the rightmost pin to ground. While it uses a single wire for data transmission, it is not compatible with the Dallas One Wire protocol. If using multiple sensors, each must have its own data pin.
Features:-
Type: AM2302.
Ultra-Low Power.
No Additional Components.
Long-Distance Signal Transmission.
All Calibration, Digital Output & Completely Interchangeable.
Relative Humidity & Temperature Measurement.
Humidity Measurement Precision: 2-5% RH.
