About this item

The DHT22 (AM2302) Digital Temperature and Humidity Sensor Module is a versatile and cost-effective solution for measuring environmental conditions in various applications. Utilizing a capacitive humidity sensor and a thermistor, it provides accurate digital readings of both temperature and humidity without the need for additional components. It can measure temperatures from -40°C to 80°C and humidity levels from 0% to 100% relative humidity (RH). The sensor offers high accuracy with temperature precision of ±0.5°C and humidity accuracy of ±2% RH, ensuring reliable data for precise control systems. Featuring digital output, it delivers calibrated signals that simplify integration with microcontrollers and reduce the complexity of analog-to-digital conversion. Designed for low power consumption, the DHT22 is suitable for battery-powered devices and remote monitoring systems. Its compact design allows easy integration into space-constrained projects. Ideal for applications such as weather stations, HVAC systems, and environmental monitoring devices, the sensor comes with a connecting cable for straightforward setup and includes a 15-day warranty against manufacturing defects.
