The DHT22 (also known as AM2302 or RHT03) is a high-accuracy digital temperature and humidity sensor with a single-wire interface. Pre-calibrated and mounted on a breadboard-compat ible module, it requires no additional components to start measuring environmental conditions immediately. Compared to the DHT11, the DHT22 offers higher precision (0.1 resolution), a wider temperature range, and better accuracy—making it ideal for applications requiring reliable environmental monitoring. Key Features High Accuracy – ±0.5°C temperature, ±2% RH humidity Fine Resolution – 0.1 degree/humidity point precision Pre-Calibrated – Digital output, ready to use Ultra-Low Power – Ideal for battery-powered projects Long-Distance Signal – Reliable over extended cable runs Excellent Stability – Consistent readings over time Breadboard Compatible – 4-pin module with included cable Specifications Model: DHT22 / AM2302 Temperature Range: -40°C to 80°C Temperature Accuracy: ±0.5°C Humidity Range: 0-100% RH Humidity Accuracy: ±2% RH Resolution: 0.1 Interface: Single-wire digital Package: 4-pin module Compatibility Raspberry Pi (all models) Arduino ESP8266 / ESP32 Micro:bit Any microcontroller with digital GPIO Ideal For Weather stations HVAC and climate control Data logging systems Greenhouse monitoring IoT environmental sensors Package Contents 1× DHT22/AM2302 Temperature & Humidity Sensor Module 1× Connection Cable Show more
