Photocell LDR Light Sensor – 4 Pieces Pack

The Photocell LDR is a light-dependent resistor designed to measure ambient light intensity by varying its resistance according to illumination levels. It features high dark resistance and low resistance under light exposure, enabling accurate light detection. The sensor operates reliably over a wide voltage range and temperature conditions. Its spectral response peaks at 540 nm, making it suitable for visible light sensing applications. Ideal for Arduino-based projects, automatic lighting control, and educational electronics experiments.
