From Makers Electronics's description

GL12528 Photoresistor Sensor LDR 1-20MΩ 12mm The GL12528 Photoresistor Sensor LDR 1-20MΩ 12mm is a compact semiconductor device designed to detect changes in ambient light levels by altering its electrical resistance. Constructed from cadmium sulfide material, this light-dependent resistor exhibits a decrease in resistance as light intensity increases, making it highly responsive to luminance variations. With a diameter of 12mm, it offers a substantial illuminated area for accurate detection, suitable for integration into various electronic circuits where space is a consideration. The sensor’s spectral response peaks at 560nm, closely mimicking the human eye’s sensitivity, which enhances its utility in applications requiring natural light perception. Encapsulated in epoxy, it provides robust protection against environmental factors, ensuring longevity and consistent performance in diverse settings. Features: Coated with epoxy for environmental protection. High reliability for consistent performance. Small volume suitable for compact designs. High sensitivity to light changes. Fast response time for quick detection. Good spectrum characteristic mimicking human eye response. Specifications: Parameter Value Diameter 12mm Maximum Voltage 250VDC Maximum Power 200mW Operating Temperature -30~+70°C Spectrum Peak Value 560nm Light Resistance (10Lux) 10-20kΩ Dark Resistance 2MΩ Gamma Value 0.6 Response Time (Rise) 30ms Response Time (Fall) 30ms Mounting Type PCB Through Hole Number of Pins 2 Applications: Camera automatic photometry for exposure control. Photoelectric control in automated systems. Indoor ray control for lighting adjustments. Annunciator devices for alerts. Industrial control for process monitoring. Light control switches for energy efficiency. Light control lamps for smart homes. Electronic toys for interactive features. Package Include: 1x GL12528 Photoresistor Sensor LDR 1-20MΩ 12mm Datasheet: GL12528

From Micro Ohm's description

The resistance of 12mm GL12528 Light Sensitive Photoresistor LDR changes with the change in the ambient light exposed on the surface of the sensor. As the light on the sensor increases then the resistance across the two leads decreases. Light Dependent Resistor is a type of photocell which finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or indoor automatic light switch; moreover, the 12mm LDR or photoresistor sensor works best in both light and dark regions. The photo-resistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it without an LDR/photo-resistor. Two Cadmium Sulphide PhotoConductive Cells with spectral responses similar to that of the human eye. Cell resistance falls with increasing light intensity. Applications of this product include smoke detection, automatic lighting control, batch counting, and burglar alarm systems. Furthermore, some of the applications are given below. Analog Applications: Camera exposure control Auto slide focus – dual cell Photocopy machines – the density of the toner Colorimetric test Equipment Densitometer Electronics scales – dual cell Automatic gain control – modulated light source Automated rearview mirror Digital Applications: Automatic headlight dimmer Nightlight control Oil burner flame out Streetlight control Absence/presence (beam breaker) Position sensor Other applications: Annunciator Camera automatic photometry Electronic toy Industrial control Light control Light control lamp Photoelectric control Switch To know more about photo-resistor, click here.
