LDR SENSOR

The LDR Sensor Module is an electronic sensor used to measure the intensity of ambient light. It operates using a Light Dependent Resistor (LDR), whose resistance changes according to the amount of light falling on its surface. The sensor provides analog or digital output signals, allowing easy interfacing with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC. It offers low power consumption, fast response, and adjustable sensitivity, making it suitable for automatic light detection and control. Due to its simplicity and reliability, the LDR Sensor Module is widely used in automatic street lighting, smart home automation, light intensity monitoring, solar tracking systems, security systems, and IoT-based environmental monitoring applications.
