Description

A PLDR (Photo Light Dependent Resistor) sensor, commonly known as an LDR (Light Dependent Resistor), is a light-sensitive component that changes its resistance based on the intensity of light falling on it. When exposed to bright light, its resistance decreases, allowing more current to pass through; in darkness, its resistance increases, reducing current flow. This property makes PLDR sensors ideal for applications like automatic street lights, solar garden lights, and light-sensitive alarms. They are affordable, energy-efficient, and easy to integrate with microcontrollers. PLDR sensors help automate lighting systems by detecting ambient light levels and responding accordingly, enhancing convenience and power savings.
