As light increases, the resistance across its leads decreases; conversely, resistance rises in low light or darkness. This responsive behavior makes the device ideal for streetlights, night lamps, and solar detection systems. Furthermore, quick response under both bright and dim environments boosts versatility in automatic control.
Built with Cadmium Sulphide (CdS) photo-conductive cells, its spectral response closely matches that of the human eye. It reacts rapidly to changing lighting conditions and provides stable readings, making this ldr resistor well-suited for burglar alarms, smoke detection, and batch counters.

Description
12mm LDR Resistor Photoresistor Photo Cell 12528 GL12528
The 12mm GL12528 LDR Sensor is a highly reliable ldr resistor designed to vary resistance based on ambient light intensity, which makes it valuable in automation projects. Thanks to an affordable ldr sensor price and simple integration with an ldr resistor circuit, it is commonly used for daylight-based switching systems and smart lighting.As light increases, the resistance across its leads decreases; conversely, resistance rises in low light or darkness.
