How does a motion sensor light switch work?

How does a motion sensor light switch work?

Motion sensor light switches use one of two sensors to detect occupancy in a room: passive and active. If the sensor detects heat, it triggers the switch to turn on. If the sensor detects no body heat after a certain amount of time, it triggers the switch to turn off.

What is occupancy sensor switch?

Occupancy sensors turn the lights on and off automatically, while vacancy will only turn the lights off and need to be manually turned on. Both can be programmed to turn the lights off after a set amount of time after movement has ceased.

How do occupancy sensors for lighting work?

Occupancy and vacancy sensors are devices that detect when a space is unoccupied and accordingly automatically turn OFF (or dim) the lights, thereby saving energy. The device may also turn the lights ON automatically upon detecting the presence of people, providing convenience and a potential security aid.

Can I use sensors to turn my lights on and off?

Turn lights on and off with motion One of the most classic uses for a motion sensor is to use it to activate lights to turn on or off automatically. For example, if someone is walking up through your front yard at night, your motion sensors can automatically turn your porch lights on.

How are occupancy sensors wired?

Occupancy sensor switch wires each have two black wires, (or one black and one red) and ground (green). One of the black line wires connects to line voltage from the panel, the other black (or red) load wire connects to the light(s). Each black wire can be a line or a load.

How long do occupancy sensors last?

On average, a motion detector light will stay on for up to 20 minutes. That amount of time is extended each time a sensor detects fresh movement, so it is possible for a motion detector light to stay on for much longer than 20 minutes at a time.

What is the difference between vacancy sensor and occupancy sensor?

An occupancy sensor turn lights ON automatically upon the detection of motion then turns the lights OFF automatically soon after an area is vacated. A vacancy sensor does not offer an option of automatically turning lighting on requiring a manual button press from the occupant (manual/vacancy mode).

How do you adjust a sensor light switch?

Step 1: Turn your light switch to the on position, then flip it off for two to three seconds. Turn the switch on and check your lights. If this does not work, proceed to step two. Step 2: Turn your light switch on and off quickly, hitting each position four times.

Are occupancy sensors required?

Occupancy sensors per C405. 2.2. 2 are required in all classrooms, conference/meeting rooms, employee lunch and break rooms, private offices, restrooms, storage rooms, janitorial closets, and other spaces 300 sq ft or smaller enclosed by ceiling height partitions.

What is occupancy sensor?

Occupancy Sensors. An occupancy sensor is a device that is capable of detecting and/or recording the amount of people in a room or area. Occupancy sensors are most often used to determine how many people are in an area that may restrict the total occupancy or in a system that turns lights/other accessories off when no one is using them.

What is a ceiling occupancy sensor?

The Passive Infrared (PIR) Technology senses occupancy by detecting the difference between heat emitted from the human body in motion and the background space.

  • and other common areas where there are high levels of occupant motion.
  • Off automatically when people enter or leave a room

    How do you install a motion sensor light switch?

    Installing The Motion Sensor Switch. Attach the ground wire, green or bare of insulation, in the box to the green screw or green wire on the new switch. If wire nuts are being used to splice wires together, as in the switch pictured, screw the nut on and, holding the nut, tug firmly on each wire separately.
