Description
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. Features • Light-dependent resistor technology • High dark resistance up to 0.5 MΩ • Low resistance under illumination • Peak spectral response at 540 nm • Wide DC voltage handling • Stable operation over temperature range • Simple two-lead passive component • Suitable for Arduino and microcontrollers LDR - Light dependent resistor • LDR Datasheet Tutorials • How to Use a Photoresistor (Light Sensor) with Arduino (Lesson #27)
