What is an occupancy sensor and how does it work?

An occupancy sensor detects when people are present in a space and measures how that space is used over time. It works by using technologies like infrared, ultrasonic or radar sensing to count people entering, exiting or occupying an area—without capturing personal data.

At Density, our occupancy sensors use anonymous depth or radar data, not cameras, to provide real-time, highly accurate headcounts in offices, universities, airport lounges and other shared spaces. The data is used to analyze patterns of usage, identify underused areas and support decisions about office layout, cleaning schedules, energy efficiency and real estate planning.

Why are occupancy sensors important?

  • Improve space utilization: See which areas are overused or underused.
  • Enhance employee experience: Avoid crowding and provide better amenities.
  • Reduce real estate costs: Identify opportunities to downsize or reconfigure.
  • Support return-to-office strategies: Make data-driven decisions about hybrid work.

How Density’s occupancy sensors are different

  • Privacy-first: No cameras or personally identifiable data.
  • Accurate and scalable: Used by Fortune 100 companies in global workplaces.
  • Real-time insights: Understand how every square foot is used, hour by hour.
  • API-ready: Integrates with workplace apps and dashboards.

Summary

Occupancy sensors track how many people use a space, when and how often. They help companies optimize their workplaces for cost, comfort and performance—especially in today’s flexible work environment.

How do I know if my office space is being wasted?

You can tell if your office space is being wasted by measuring how often each space is used—and occupancy sensors provide the real-time data you need to find out.
If desks, meeting rooms, or entire floors are consistently empty or underutilized, that’s space (and money) going to waste. Tools like Density’s Waffle and Atlas help companies assess usage accurately so they can cut costs and improve the workplace experience.
