Description Light Dependent Resistor (LDR) is a variable resistor that changes resistance based on light intensity. It is commonly used in automatic lighting, ambient light sensing, and electronic circuits. 4 LDR Light Sensor module consists of four light-dependent resistors that detect changes in ambient light levels, making it useful for robotics, solar tracking, and smart lighting applications. 4 LDR sensor array is designed for detecting directional light intensity, ideal for projects like solar tracking, line-following robots, and light-sensitive automation. 4 LDR sensor system can be used for brightness control, motion-activated lighting, and security alarms by responding to varying light conditions.
