DHT11 Sensor – Humidity and Temperature Sensor

The DHT11 Sensor is a low-cost digital sensor designed to measure relative humidity and temperature in the surrounding environment. It uses a capacitive humidity sensing element and a thermistor to provide accurate data. The sensor includes an internal signal-processing chip that converts raw analog values into calibrated digital output, eliminating the need for extra components or complex signal conditioning.

With a single-wire serial interface, the DHT11 is easy to integrate with platforms like Arduino, Raspberry Pi, and other embedded systems. The module offers reliable long-term performance and fast response time, making it suitable for indoor atmospheric monitoring, environmental control systems, automation, and IoT applications.
