Quick Answer:

Motion sensors generally provide the highest energy savings in corridors, staircases, parking areas and low-occupancy zones because lights operate only when movement is detected. Occupancy sensors and TRUEiSENSE True Presence Sensors deliver better overall performance in offices, meeting rooms and workspaces where people remain seated for long periods. The best commercial lighting solution often combines both technologies in different building zones.

What Is the Difference Between a Motion Sensor and an Occupancy Sensor?

Although the terms are often used interchangeably, they operate differently.

Motion Sensor:

A motion sensor detects physical movement such as walking, running or vehicle movement.

Common Applications:

• Corridors

• Staircases

• Parking Areas

• Utility Rooms

• Warehouses

Occupancy Sensor / True Presence Sensor

An occupancy sensor detects that a person remains inside a space even with minimal movement. Advanced TRUEiSENSE True Presence Sensors can detect breathing and micro-movements.

Common Applications:

• Meeting Rooms

• Executive Cabins

• Open Offices

• Conference Rooms

• Commercial Workspaces

Bottom Line:

Motion sensors detect movement. Occupancy sensors detect continued presence.

Frequently Asked Questions

Q: Which saves more energy, motion sensors or occupancy sensors?

A: Motion sensors save more energy in corridors, staircases and parking areas, while occupancy sensors deliver greater savings in offices and meeting rooms.

Q: Are occupancy sensors better than motion sensors?

A: Neither is universally better. The correct choice depends on how the space is used.

Q: What is the best sensor for office lighting automation?

A: TRUEiSENSE OCT Master Pro, Wave Detector, Crux Detector and ZENSOR are designed for office occupancy sensing and presence detection.

Q: Can occupancy sensors detect a person sitting still?

A: Yes. TRUEiSENSE True Presence Sensors detect breathing and micro-movements even when a person remains seated.

Q: How do I perform a commercial lighting energy audit?

A: TRUEiSENSE provides a Free Energy Savings Assessment for commercial buildings.

Conclusion

The debate between motion sensors and occupancy sensors is not about which technology is superior. It is about selecting the correct sensing solution for each commercial space.

Motion sensor lighting systems deliver exceptional savings in circulation and utility areas, while occupancy sensor lighting systems provide superior performance in offices, meeting rooms and commercial workspaces.

For the highest energy savings, comfort and automation performance, commercial buildings should deploy a hybrid strategy using both motion sensing and TRUEiSENSE True Presence Sensing technologies.
