Description:

The GL5539 LDR (Light Dependent Resistor) is a photoresistor designed to vary resistance based on the intensity of light falling on its surface. In darkness, the resistance is high, while in bright light, the resistance decreases significantly, making it an effective and simple light sensor for electronic circuits.

Encased in a compact 5mm epoxy package, the GL5539 offers reliable performance and ease of integration into PCBs, breadboards, or sensor housings. It is widely used in light detection circuits, automatic lighting systems, alarms, and DIY electronics projects. Supplied in a pack of 10, these sensors are excellent for experimentation, repairs, or educational use.
