The LDR 5516 Photoresistor is a light-dependent resistor designed to detect changes in light intensity. Its resistance decreases when exposed to light and increases in darkness, making it ideal for light sensing applications.

This component is widely used in Arduino and electronics projects for automatic lighting systems, brightness detection, and energy-saving devices. It is simple to use and can be easily integrated into circuits using a voltage divider configuration.

The LDR 5516 offers stable performance, fast response to light changes, and high sensitivity, making it suitable for both beginner and advanced electronics applications.
