Photoresistors (103)

Photoresistors, also known as light-dependent resistors (LDRs), are sensors that change their resistance based on the intensity of light falling on them. They are used in various applications, including light meters, street lighting, alarm systems, and automatic lighting controls. Photoresistors are valued for their simplicity, reliability, and cost-effectiveness. They provide an easy way to detect changes in light levels, enabling automatic control of lighting and other light-sensitive systems.
