Keystone KTS-PIR2-UV-KO PIR Occupancy Sensor for High Bay Fixtures, 120-277V, 0-10V Dimming

Motion sensor switches utilize infrared radiation to monitor their surroundings. They emit energy forms such as light, microwaves, or sound to detect changes caused by movement. Most systems used in lighting and security are passive, meaning they primarily detect the infrared energy emitted by warm objects like human bodies.

Occupancy sensors and vacancy sensors are both used for detecting presence in a room, but they operate differently. Occupancy sensors automatically turn on the lights when someone enters a room and turn them off when no presence is detected after a set period. In contrast, vacancy sensors require someone to manually turn on the lights, but will automatically turn them off when the room is empty.

The primary distinction between a motion sensor light switch and a traditional light switch lies in their methods of activation. A traditional light switch requires manual operation to turn the lights on or off. Conversely, an occupancy sensor automatically activates the lights when someone enters the room and turns them off when it no longer detects any presence.

Occupancy sensors are designed to detect the presence of individuals or animals in a space and activate the lights accordingly, which can be combined with daylight sensors to enhance energy efficiency. On the other hand, daylight sensors adjust the lighting based on the natural light available, reducing the use of artificial lighting when not necessary.

Yes! Most motion sensors have adjustable sensitivity settings. This allows you to fine-tune the device to prevent false triggers or increase responsiveness in larger spaces.
