DHT22 Humidity and Temperature Sensor Module

The DHT22 is a high-performance digital sensor designed for precise measurement of temperature and humidity. It features a capacitive humidity sensor and a thermistor for accurate and reliable readings. The DHT22 offers a wide measurement range, with humidity accuracy of ±2% and temperature accuracy of ±0.5°C, making it suitable for applications requiring precision.

This sensor operates on a 3.3V–5.5V power supply and communicates using a simple single-wire digital interface, ensuring easy integration with microcontrollers like Arduino, Raspberry Pi, and other systems. Its compact size, low power consumption, and durable build make it ideal for weather stations, environmental monitoring, HVAC control, and smart home systems.

The DHT22 also supports long-term stability, operates in a wide temperature range (-40°C to 80°C), and has a humidity range of 0% to 100%. Its pre-calibrated design eliminates the need for complex setups, providing reliable data right out of the box.
