5 mm LDR (Light Dependent Resistor)

5 mm LDR (Light Dependent Resistor)

The 5 mm LDR (Light Dependent Resistor) is a photoresistor that changes its resistance based on the intensity of light falling on it. It has a 5 mm diameter sensing area and is ideal for light-sensing applications such as automatic street lighting, light meters, and alarm systems. When exposed to light, its resistance decreases, and in darkness, the resistance increases, making it suitable for light detection circuits and educational projects.
