Description
The GL12528 12mm Light Dependent Resistor (LDR) is a passive light sensor whose resistance changes according to the surrounding light intensity. As light increases, resistance decreases; in darkness, resistance increases.
These LDRs are widely used in automatic lighting systems, light/dark detectors, street light controllers, alarm systems, and Arduino-based projects. With a 12mm sensing surface, they offer good sensitivity and stable performance. This pack includes 2 pieces, perfect for prototyping and small projects.
