Working Principle

The DHT11 sensor uses a capacitive humidity sensor and a thermistor to measure surrounding environmental conditions. It processes these signals through a small microcontroller embedded in the module and sends digital data to external devices using a single-wire communication protocol.

This makes it easy to integrate with Arduino, Raspberry Pi, and other microcontrollers, as users only need a single data pin to access both temperature and humidity values. The simple design ensures that even beginners can successfully build weather monitoring or automation projects with minimal effort.
