Light Dependent Resistor: A Comprehensive Guide | Electrical4U
A light-dependent resistor (LDR) is a passive component that changes its resistance based on light intensity. Also known as photoresistors, photocells, or photoconductors, LDRs are made from semiconductor materials with high resistance in darkness and low resistance in light. They are commonly used as light sensors in street lighting, alarm…
