The 10mm LDR (Light Dependent Resistor) is a passive light sensor that changes its resistance based on the intensity of light falling on it. Commonly used in light-sensitive circuits, automatic street lights, solar garden lights, and Arduino projects, this component allows you to detect and react to changes in ambient light.
Its large 10mm sensing area provides better sensitivity, making it ideal for both indoor and outdoor light detection. Popular in the Bangladesh electronics market, this LDR is a simple yet powerful component for building light automation systems.
