DHT22 (AM2302) Digital Temperature & Humidity Sensor Module
Calibrated digital composite sensor providing ultra-reliable relative humidity and temperature measurements with single-bus digital signal output.
DHT22 (AM2302) Digital Temperature & Humidity Sensor Module is an authentic, engineering-grade hardware component designed for prototyping, robotics, and academic research. Includes verified schematics, pre-tested hardware, and nationwide express shipping across Pakistan.
The DHT22 (AM2302) is an industrial-grade digital relative humidity and temperature sensor. It offers significantly higher accuracy, broader measurement ranges, and greater stability compared to the basic DHT11.
Key Engineering Features:
- Full-Range Humidity Sensing: Measures from 0% to 100% RH with ±2% typical accuracy.
- Wide Temperature Operating Range: Measures from -40°C to +80°C with ±0.5°C accuracy.
- Digital Single-Bus Signal: Clean calibrated digital output requires only 1 microcontroller GPIO pin.
- Integrated Breakout Board: Includes on-board pull-up resistor and decoupling capacitor for noise immunity.
Common Engineering Applications:
- Smart greenhouse automation and environmental climate control
- HVAC monitoring and HVAC thermostat controllers
- IoT server room temperature/humidity alert telemetry
- Egg incubator automated humidity and temperature management
