LDR 5mm - Photocell
The 5mm LDR (Light Dependent Resistor), or photocell sensor, is a highly sensitive component that detects ambient light and adjusts resistance accordingly. It is ideal for automatic lighting, brightness control, and energy-efficient circuits. The resistance decreases in bright light and increases in darkness, making it suitable for day/night detection and smart automation systems.
This compact and reliable LDR is widely used in industrial, home automation, and electronic circuits for light intensity measurement and control applications.
