Motion SensorLighting accounts for 40% of all electrical usage in a typical commercial building. Due to poor energy conservation practices and human oversight, lights are often left on in areas that are otherwise unoccupied. Occupancy sensors will automatically turn lights on when a presence is detected and automatically shut off lights when the room has been vacated. They utilize a passive infrared sensor that detects the difference in heat between a human body and the background and is well suited for areas with one entryway. Implementing occupancy sensors will eliminate needless expenditure of energy and may result in significant savings.

GEI’s occupancy sensors are an unobtrusive and aesthetically pleasant replacement for the typical wall switch. The sensing range and cut off time are customizable to ensure user comfort and maximize energy savings. Reduce fixed operational costs by upgrading to an automatic system today!

Passive Infrared (PIR)

  • React only to energy sources such as the human body from within their control areas.
  • Best for
    – enclosed offices with a clear view of entire area – a wall switch replacement
    – Areas with high air flow: computer rooms, laboratories, etc.
    – Warehouses, hallways, high-ceiling-mount applications – Areas that require direct line-of-sight viewing – Spaces that need to mask off unwanted detection in certain areas
