DHT22 / AM2302 High-Precision Digital Temperature and Humidity Sensor

DHT22 / AM2302 High-Precision Digital Temperature and Humidity Sensor

Get highly accurate and reliable environmental readings with the DHT22 / AM2302 Digital Temperature and Humidity Sensor. As a significant upgrade from the DHT11, this sensor offers a wider measurement range and greater precision, making it the superior choice for projects where accuracy is critical.

The DHT22 (also known as the AM2302) is a fully calibrated digital sensor that measures both temperature and relative humidity. It utilizes a high-performance 8-bit microcontroller and advanced sensing elements to deliver fast response times and excellent long-term stability. Like its predecessor, it communicates over a single data wire, simplifying integration with microcontrollers like Arduino and ESP32.

If your project demands more than just a basic reading—whether for scientific data logging, precise climate control, or a high-quality weather station—the DHT22 is the perfect sensor for the job.

Key Features:

• High Precision: Offers superior accuracy compared to the DHT11.
• Wide Measurement Range: -40 to 80°C for temperature and 0-100% RH for humidity.
• Excellent Accuracy: +/- 0.5°C for temperature and +/- 2% RH for humidity.
• Digital Output: Calibrated digital signal output over a single wire.
• Operating Voltage: 3.3V to 5.5V.

Applications:

Perfect for high-accuracy data loggers, professional-grade weather stations, industrial control systems, agricultural monitoring, medical equipment, and any application requiring precise and reliable temperature and humidity data.
