Product Description
- Introducing the LDR 5MM Light Dependent Resistor (Pack of 10), a versatile sensor that reacts to changes in ambient light levels. Commonly referred to as an LDR, this photocell is widely used in applications such as automatic light switches for both indoor and outdoor settings.
- The 5mm LDR sensor performs well in both bright and dim environments, making it suitable for a variety of uses. It operates by adjusting its resistance based on the light intensity it detects—resistance decreases as light levels increase.
- Featuring two Cadmium Sulphide (CDs) photoconductive cells with spectral responses similar to the human eye, this sensor delivers reliable performance. Its applications include smoke detection, automatic lighting control, batch counting, and burglar alarm systems.
- Enhance your light sensing capabilities with the LDR 5MM Light Dependent Resistor, offering a straightforward and effective solution for monitoring ambient light levels in multiple environments.
