The LDR (Light Dependent Resistor) Sensor Module is a simple yet effective device used to measure light intensity. It is designed to detect changes in ambient light and provide corresponding analog and digital outputs, making it versatile for various automation and control applications.
The module uses an LDR (photoresistor) as its primary sensing component, which changes its resistance based on light levels. The analog output provides a signal proportional to the light intensity, while the digital output indicates whether the light level exceeds a preset threshold, adjustable via the onboard potentiometer.
Powered by a typical voltage of 3.3V to 5V, the LDR Sensor Module is compatible with microcontrollers like Arduino, Raspberry Pi, and ESP32. It is compact, easy to integrate, and ideal for applications such as automatic street lighting, daylight detection, light-following robots, and brightness-controlled displays.
With its low power consumption and high sensitivity, the LDR Sensor Module is a reliable choice for projects requiring light measurement or control.
