Motion Sensor High Bay Overview
Many high bay lighting fixtures now feature motion sensor technology, either as an integrated unit or an optional add-on. This new feature has been increasing in popularity over the past decade, due to its effectiveness as well as ease of installation. In the past, multiple motion sensors would be required to be mounted throughout a facility to activate or deactivate lights, which would then independently cycle the power on and off to the lighting system.
With current motion sensor technology being integrated into the fixtures themselves, this eliminates the extra hassles and costs associated with setting up an independent motion sensor system. It also allows for more precise measurement of motion inside a room, which means only the lights in the immediate vicinity of individuals in the room will illuminate versus the entire room at once. This saves electricity and extends useful fixture life, saving a considerable amount of costs over the lifetime of the fixture.
About High Bay Motion Sensors
High bay motion sensors mount directly into a lighting fixture and provide a multi-level control based on motion and/or daylight. It controls 0-10 VDC LED drivers or dimming ballasts, as well as non dimming ballasts. Our high bay motion sensors are rated for wet and cold locations. All control parameters are adjustable via a wireless configuration tool capable of storing and transmitting sensor profiles.
It’s important to note that certain motion sensors are only compatible with specific high bay lighting fixtures. It’s always best to check the manufacturer along with the product specification sheet in order to ensure that a motion sensor will operate correctly with a specific fixture. For instance, our commercial LED occupancy motion sensor is compatible with particular product lines. For the benefit of the user, we’ve outlined these directly on the product page.
Occupancy Light Sensor
Motion sensors are also commonly referred to as occupancy light sensors or photosensors. One popular example of this is Keystone’s PIR Occupancy Sensor which we carry in our store. Keystone’s PIR sensors intelligently signal when to turn the lights on and off using passive infrared technology. Keystone sensors provide daylighting, adjusting automatically to save on energy costs. These sensors are also wet location rated and have on/off functionality with present hold times of 1 minute or 5 minutes.
Motion Sensors & Energy Cost
Motion sensors save energy by turning on lights or other energy consuming devices only when a person or object is present in a room. When the room is empty, the lights or appliances are automatically turned off, reducing energy consumption. Motion sensors are especially effective in corridors and stairwells, as well as in rooms used intermittently. They are also used to control heating and cooling systems, so that the temperature is only adjusted when someone is present in a room.
Furthermore, motion sensors can be used to detect the presence of people in public spaces, such as parks and shopping centers, in order to adjust the lighting accordingly. As a result, motion sensors save energy and money, and help to reduce the environmental impact of electricity consumption.
A study was conducted by the Journal of the Illuminating Engineering Society on the lighting operation and workspace occupancy patterns across numerous commercial lighting systems. According to the study,
…”Studies that examined combined motion and daylight sensors reported a wider range and higher average energy savings, from 13% to 73.2%” (Journal of the Illuminating Engineering Society, September 2013, An Analysis of the Energy and Cost Savings Potential of Occupancy Sensors for Commercial Lighting Systems)
