Humidity & Temperature Sensor Module | DHT22

The DHT22 is a high-accuracy digital sensor that measures both temperature and humidity, offering better performance than the basic DHT11. With a wider measurement range and improved precision, it’s well-suited for professional projects where reliability is important.

It communicates using a simple digital signal, making it easy to connect with Arduino, ESP8266/ESP32, Raspberry Pi, and other microcontrollers.

Highlights

• Temperature Range: –40°C to +80°C

• Humidity Range: 0% to 100% RH

• Accuracy: ±0.5°C (temp), ±2–5% RH (humidity)

• Operating Voltage: 3.3 V – 5 V

• Output: Digital signal (single wire)

• Better performance than DHT11 (wider range + higher accuracy)

• Comes with cable for easy wiring

💡 Ideal for: Weather stations, HVAC monitoring, smart agriculture, data logging, and IoT projects requiring accurate climate sensing.
