EnOcean-Powered Motion Sensors Optimize Office and Hotel Spaces
November 3, 2025
Effective occupancy detection is essential for improving energy efficiency, space optimization, and occupant well-being in commercial buildings, hotels, and offices.
With energy-harvesting wireless technology from EnOcean-, building operators can implement flexible, maintenance-free solutions that go far beyond the limitations of traditional wired systems.
By combining wireless PIR motion detectors and illumination sensors based on the EnOcean standard with Contemporary Controls’ EnOcean to BACnet Gateway, this integrated solution delivers reliable occupancy detection and intelligent energy management — seamlessly connecting EnOcean devices with building automation systems via BACnet/IP.
Key Components
EnOcean-based Wireless PIR Motion Detectors
These sensors detect infrared radiation changes caused by human movement and communicate wirelessly using the EnOcean protocol. Ceiling- or wall-mounted, they provide flexible installation with no wiring required, adjustable sensitivity, and detection ranges up to 5 meters — ideal for a wide range of spaces.
Integrated EnOcean Illumination Sensors
Operating alongside motion detectors, EnOcean-powered illumination sensors measure ambient light levels. This enables smart lighting control that responds to both occupancy and natural light conditions — reducing energy consumption while ensuring occupant comfort.
EnOcean to BACnet Gateway by Contemporary Controls
This gateway enables seamless bidirectional communication between EnOcean wireless devices and BACnet/IP networks. It serves as the bridge between EnOcean-based devices and building management systems, simplifying integration and system scalability.
How It Works
- Occupancy Detection:
EnOcean motion sensors detect occupancy and wirelessly transmit the data using the EnOcean protocol. - Illumination Measurement:
Light sensors measure real-time brightness levels, enabling dynamic lighting control based on occupancy and daylight. - Energy Management:
When spaces are unoccupied, the system automatically adjusts lighting and HVAC settings, optimizing energy use without compromising comfort. - System Integration:
The EnOcean to BACnet Gateway translates EnOcean wireless signals into standard BACnet objects, allowing full visibility and control through existing building management platforms. - Space Utilization Insights:
Occupancy data collected from EnOcean sensors provides valuable insights into how spaces are used — supporting data-driven decisions for flexible office layouts and energy planning.
Efficient, Scalable, and Sustainable
Wireless occupancy detection systems built on EnOcean technology provide an energy-efficient, maintenance-free, and easily scalable solution for modern buildings. By combining self-powered EnOcean sensors with standardized building automation protocols, this system ensures reliable occupancy monitoring, seamless integration, and outstanding performance in both new installations and retrofit projects.
With EnOcean, building operators gain a powerful toolset for reducing energy consumption, enhancing occupant comfort, and maximizing space utilization — all without the need for batteries or complex wiring.
