Occupancy Sensor Light Switch

What is the definition of a occupancy sensor light switch? This is a device that uses an infrared or microwave detector to detect when someone enters an area and automatically turns on or off the lights as needed. This type of switch is most commonly used in public areas, such as offices and warehouses, where people may not be present all the time. The switch is designed to save energy by only turning the lights on when they are needed and turning them off when they are not. The switch has a range of sensitivity, which determines how far away the sensor can detect the presence of a person. It can also be programmed to turn on the lights at a certain time and to turn them off at a specific time. Occupancy senssensor light switches can provide energy savings, safety, and convenience to any home or business.
