The 5528 Light Dependent Resistor (LDR) is a photosensitive sensor that detects changes in ambient light intensity by varying its electrical resistance. As light levels increase, the resistance decreases, allowing the sensor to accurately measure brightness for a wide range of electronic and automation applications.
Compact, reliable, and energy-efficient, the 5528 LDR is widely used in Arduino, ESP32, Raspberry Pi, and other microcontroller projects. It is easy to integrate into electronic circuits and is ideal for automatic lighting systems, light meters, security devices, and smart home applications.
Designed for consistent performance and long service life, this photoresistor provides a simple and cost-effective solution for detecting and responding to changes in environmental lighting conditions.
