From the shop's description

GL7537-2 Photoresistor Sensor LDR 30-50kΩ 7mm 2Pcs The GL7537-2 Photoresistor Sensor LDR 30-50kΩ 7mm 2Pcs is a 7mm cadmium sulfide light sensor designed to change its resistance based on ambient light intensity. With a resistance range of 30–50kΩ, it offers reliable sensitivity for detecting light variations in different environments. This LDR is widely used in automatic brightness control, light-activated switching, solar garden lights, and DIY electronic projects. The compact round package makes it easy to integrate into circuits, while its fast response to light changes ensures stable performance. This pack includes 2 pieces, making it suitable for both experimentation and practical applications. Features 7mm round epoxy-coated head for higher light sensitivity. Resistance range: 30–50kΩ at 10 lux illumination. Reliable and stable performance under varying light conditions. Fast response time to changes in ambient light. Easy to integrate into light control and sensing circuits. Durable construction for long service life. Supplied in a convenient 2-piece pack.
