Wireless Room Occupancy Sensor – Pressac

Automatically detect occupancy in meeting rooms, offices, spaces or zones

  • Detect live space occupancy – Access live occupancy data for demand-controlled room booking, lighting and HVAC control
  • Get updates as occupancy changes – Track usage to better manage space bookings and cleaning
  • Track space usage over time – Monitor space utilisation over time to make better planning decisions

How our room occupancy sensors work

Our wireless motion sensors detect and monitor the presence of people, in real time. The small, battery-powered sensors simply stick to the ceiling, enabling you to detect real-time presence and continually monitor room occupancy.

They detect passive infrared radiation (PIR) emitted by people, within a 360 degree radius. When a person enters the sensor’s field of view, the sensor detects motion and tells you someone is present within that space. The sensor continues to monitor the space and can send you regular occupancy updates.


  • Small, discreet sensors simply stick to the ceiling
  • Passive infrared (PIR) sensor detects motion within 360 degree field
    of view, up to 6 meters distance
  • Field of view will depend on ceiling height Based on a typical 2.5m ceiling height, approx. 64 degree detection angle resulting in estimated
    5m detection
  • Instant updates when occupancy detected, plus status updates
    can be configured between 10 minutes and 5 hours
  • Absence time out can be configured between 2 and 60 minutes
  • GDPR and privacy compliant solution: no images or personal information stored or transmitted
  • Ultra-low power technology. Battery life typically 3–5 years. USB-powered variant available
