AJMRTC 100Pcs GL5528 5mm Light Dependent Resistor LDR Photoresistor, CdS Photoconductive Resistor for Light Intensity Detection, Arduino Smart Lighting DIY Project

AJMRTC GL5528 photoresistor (LDR) is a classic CdS light sensing component widely used for ambient light detection. Its resistance decreases as light becomes brighter and rises sharply in darkness. It works together with a fixed resistor to form a voltage divider circuit, converting light intensity into analog voltage signals readable by Arduino, ESP32, STM32 and other microcontrollers. The 5mm epoxy encapsulated body protects the internal photoconductive layer. It has fast light response speed and stable performance under normal visible light. You can build automatic night lights, street light control, light tracking robots, brightness meters and smart home light trigger systems. This listing contains 100 pieces, which meets the demand for multi-channel light sensing testing, teaching experiment kits and spare component inventory.
