2. Lighting control system - Wikipedia

   en.wikipedia.org/wiki/Lighting_control_system

   The term lighting control system refers to an intelligent networked system of devices related to lighting control. These devices may include relays, occupancy sensors, photocells, light control switches or touchscreens, and signals from other building systems (such as fire alarm or HVAC). Adjustment of the system occurs both at device locations ...

3. Occupancy sensor - Wikipedia

   en.wikipedia.org/wiki/Occupancy_sensor

   Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.

4. Motion detector - Wikipedia

   en.wikipedia.org/wiki/Motion_detector

   A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.

   These cabinet lights can detect motion up to 10 feet away. They have 30 LEDs that produce a warm light up to 200 lumens. It's more than enough to see by, but doesn't have that cold quality that ...

6. Passive infrared sensor - Wikipedia

   en.wikipedia.org/wiki/Passive_infrared_sensor

   A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.

7. Intelligent sensor - Wikipedia

   en.wikipedia.org/wiki/Intelligent_sensor

   Because the tasks are performed by microprocessors, any gadget which mixes a sensor and a microprocessor is usually called an intelligent sensor. To qualify as an intelligent sensor, the sensor and processor must be part of the same physical unit. A sensor whose only function is to detect and send an unprocessed signal to an external system ...
