VAT inclusive; Computed calculations added locally.
Overview
The DHT22 Digital Temperature and Humidity Sensor Module AM2302 is an easy-to-use digital environmental sensor designed for measuring surrounding temperature and relative humidity. It combines a capacitive humidity sensor and a thermistor to measure environmental conditions and provides the readings through a digital data output.
Because the sensor uses a digital interface, it does not require an analog input pin or external analog-to-digital converter. This makes the DHT22 a practical choice for Arduino, ESP32, Raspberry Pi, IoT, home automation, weather monitoring, and other DIY electronics projects.
