GL5528 Photoresistor Sensor LDR 8-20kΩ 5mm
The GL5528 Photoresistor Sensor LDR 8-20kΩ 5mm is a light-dependent resistor that changes its resistance based on the intensity of light falling on it. With a resistance range of 8–20kΩ under standard light conditions, it provides a reliable and cost-effective solution for light sensing applications. The GL5528 features a small, durable package with a fast response to varying light levels, making it suitable for automatic brightness control, light-activated switches, and simple ambient light detection systems. Its wide spectral response and high sensitivity make it an ideal choice for both consumer electronics and DIY electronics projects.
