What Does a Sensor Light Do?
A sensor light is a type of lighting fixture equipped with a sensor that detects movement, changes in light levels, or other environmental factors to automatically turn on or off. These lights are commonly used for security, energy efficiency, and convenience in both residential and commercial settings. How Do Sensor Lights Work? Sensor lights operate using different types of sensors, including motion sensors, photocells, and infrared sensors. The function of these sensors is to trigger the light when specific conditions are met. 1. Motion Sensors Motion sensor lights detect movement within a certain range and activate the light accordingly. These sensors typically use Passive Infrared (PIR) technology, which detects heat emitted by living beings. When an object moves within the detection zone, the sensor registers a change in infrared radiation and turns on the light. Motion sensor lights are commonly used in outdoor areas such as driveways, gardens, and secu...
