Product Description

DHT22 Digital Temperature & Humidity Sensor Module

= High-Precision Environmental Sensor for Arduino Projects =

The DHT22 is a high-quality digital temperature and humidity sensor, often sold as the AM2302 module. It provides superior accuracy and a wider measurement range than the popular DHT11, making it suitable for reliable environmental monitoring in weather stations and HVAC projects .

High Precision Temperature accuracy of ±0.5°C and humidity accuracy of ±2% RH for professionalgrade readings .
Wide Measurement Range Covers 40°C to +80°C and 0-100% RH, suitable for extreme environments .
The module uses a single-wire digital interface, simplifying wiring and coding compared to analog sensors .
For Arduino, use the DHT sensor library with a data pin and a pull-up resistor.
