20mm LDR Photocell Light Dependent Resistor CdS

The 20mm LDR (Light Dependent Resistor) Photocell is a high-sensitivity Cadmium Sulfide (CdS) photoresistor that changes its resistance inversely with ambient light intensity. With a compact 20mm diameter, epoxy coating for durability, and fast response time, it is ideal for automatic lighting control, light-activated alarms, brightness control, robotics, and a wide range of light-sensing applications.
