The DHT22 / AM2302 Digital Temperature and Humidity Sensor Module is a high-precision, low-cost climate monitoring breakout board designed for stable, long-term environmental tracking. Superior to the basic DHT11, this sensor delivers highly accurate relative humidity and ambient temperature data via a single-bus digital signal. Pre-mounted on a convenient 3-pin PCB with an integrated pull-up resistor, it operates smoothly on both 3.3V and 5V logic.
