![]() However, in some instances if the sensor is placed too close to a heat source such as a dryer, stove or heating vent, the heat generated may trigger the lights to turn on or prevent them from turning off. Can a motion sensor light switch be triggered by humidity or a heat source? However, the sensor sensitivity setting can be adjusted, or the sensor can be set to manual-on so it functions as a vacancy (manual-on) sensor. There is a possibility that the movement of a pet or small child within 8 feet of an occupancy motion sensor switch will trigger the lights to turn on. If I have pets, will their movement trigger the occupancy motion sensor switch to turn the lights on? Leviton's occupancy sensor switches incorporate an ambient light override setting which, when enabled, will prevent the sensor from switching the lights on when there is ample daylight in the space. If there is sufficient daylight in an area, will the occupancy sensor switch still automatically turn the lights on? Vacancy sensor switches are required by code in some States/jurisdictions such as California. They work best in rooms where you may enter and exit with your hands full or if reaching for a light switch may be difficult and possibly hazardous.Ī vacancy sensor switch is recommended for use in high traffic areas such as hallways, children’s rooms, living rooms, dining rooms and bathrooms, where people and pets frequent often and where energy savings can be achieved by turning off the lights when the space is unoccupied. Where would I use an occupancy sensor switch? Where would I use a vacancy sensor switch?Īn occupancy sensor switch is ideal in areas such as laundry rooms, garages, basements, pantries, closets, mudrooms, and storage areas where you want the convenience of the lights turning on and off automatically. What is the difference between an occupancy sensor switch and a vacancy sensor switch?Īn occupancy sensor switch automatically turns the lights on when motion is detected within the sensor viewing range and automatically turns the lights off when the room is vacant, and motion is no longer detected.Ī vacancy sensor switch, also known as a manual-on sensor, requires the user to manually turn on the lights and will automatically turn lights off when the room is vacant, and motion is no longer detected. Airflow, HVAC ducts and heat sources must also be taken into consideration because if any are too close to the sensor, they can inadvertently trigger it. Also consider the size and shape of the area and the type of activity taking place in the space. First, the space requires an unobstructed line-of-sight for accurate detection because any obstructions that block the sensors’ view can affect the detection of motion. Motion Sensor switches use passive infrared (PIR) technology to detect movement so there are a few factors to take into consideration when installing them in the home. How do motion sensors light switches work? In some States/jurisdictions like California, the building code requires them. Vacancy models require the user to manually turn the lights on and will automatically turn lights off after a set period or when motion is no longer detected. ![]() An occupancy sensor will automatically turn lights on when motion is detected, and off after a set period when motion is no longer detected. Motion sensor light switches provide hands-free lighting for added safety and convenience. Occupancy/Vacancy Sensors Frequently Asked Questions Why would I want to use a motion sensor?
