GL12528 Photoresistor Sensor LDR 1-20MΩ 12mm

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.

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.
