The 3-Pin DHT11 Relative Humidity Sensor Module is a reliable digital sensor designed to accurately measure temperature and relative humidity in a wide range of electronic and embedded system applications. Featuring a calibrated digital output, the DHT11 provides stable and accurate environmental readings while requiring only a single digital signal pin for communication.

This sensor module is widely used in Arduino, ESP32, ESP8266 NodeMCU, Raspberry Pi, STM32, AVR, PIC, and other microcontroller-based development boards. It is ideal for IoT projects, weather monitoring systems, smart home automation, greenhouse monitoring, HVAC systems, data logging, environmental monitoring, and educational electronics projects.

The integrated PCB includes the DHT11 sensor, pull-up resistor, power indicator, and a standard 3-pin interface, allowing quick and easy connection without additional external components. Its compact size, low power consumption, and simple digital communication make it a popular choice for beginners, students, makers, engineers, and professional developers.
