How do Presence and Motion Detection Improve Smart Buildings​?

Presence and motion detection systems refer to sensor-based systems that identify whether people are moving through or occupying a space. Motion detection picks up larger movements such as walking, making it suitable for corridors and circulation areas. Presence detection is more sensitive and can detect small movements like typing or shifting position, ideal for offices and meeting rooms.

These systems are commonly used to automate lighting and can also support heating or ventilation control. Presence and motion detection systems helps ensure building systems respond to real usage rather than fixed schedules. This results in more efficient operation and a better experience for occupants in residential, commercial, and public buildings.

How Do Presence Detectors Save Energy on Lighting?

Theben’s presence detectors are the ultimate solution for intelligent, energy-saving lighting control. Perfect for offices, corridors, and public buildings, our detectors also enable heating and air conditioning to be managed based on occupancy. This not only helps reduce energy costs but also significantly cuts CO2 emissions.

Our presence detectors respond to even the slightest movement and continuously monitor ambient light levels. When no movement is detected or the set brightness threshold is exceeded, the detector automatically switches off the lighting, ensuring no energy is wasted.

How Do Presence and Motion Detection Works?

Presence and motion detection systems identify movement or occupancy within a space and trigger predefined control actions. When activity is detected, connected systems such as lighting can respond automatically, providing light or function only when required.

Detection behaviour can be adapted to suit different areas and usage patterns, allowing control systems to respond appropriately to how spaces are used throughout the day.

What's the Difference Between a Motion Sensor and a Presence Detector?

The key distinction lies in sensitivity:

  • Presence detectors feature highly sensitive sensors that divide their detection area into up to 1000 zones, enabling them to pick up even the smallest movements – like someone typing at a desk. They also offer continuous light measurement, turning lights off as soon as sufficient daylight is available, even if movement continues. This maximises energy savings and reduces CO2 emissions.
  • Motion sensors (PIR sensors) are ideal for detecting larger, more obvious movements, such as someone walking through a hallway or approaching a building entrance. However, they typically measure light only once – when first activated – meaning lights can remain on unnecessarily if movement is ongoing.

How to Choose the Right Detector for Your Space?

By Room Size and Shape

Small Rooms and Cellular Offices (up to 6m span)

The PIRA T6 Mini gives a circular 360° detection area up to Ø6m (28m²) at 2.5m mounting height. This suits single offices, small meeting rooms, and storerooms where one central ceiling-mounted unit needs to cover the whole floor without dead zones. 

Standard Offices and Meeting Rooms (up to 8m span)

The PIRA T8 AP (surface-mounted) or PIRA T8 DE (recessed) covers a circular Ø8m (50m²) area at the same 2.5m mounting height. For a typical 6 x 6m office (36m²), one centrally mounted T8 covers the full room with margin to spare. Once a room exceeds roughly 7m in any direction, a single T8 starts to leave weak detection at the corners, so check actual room dimensions against the Ø8m circle rather than just floor area.

Larger open-plan spaces (up to 12m span)

The LUXA 103 S360-101-12 or S360-100-12 extends coverage to Ø12m (113m²) at 3m mounting height. For open-plan offices between 50m² and 113m², this is a single-unit solution rather than needing two T8s. Above 113m², plan for multiple units with overlapping coverage rather than relying on one detector at the edge of its range, since sensitivity typically drops off toward the outer limit of the stated detection radius.

Rectangular spaces: Corridors and Long rooms
  • The PIRA TC AP or PIRA TC DE covers a 25 x 3m (75m²) rectangular footprint at 2.5m mounting height, ideal for standard corridors.
  • The LUXA 103 S360-100-28 extends this to 28 x 5m (140m²) at 3m mounting height, suited to wider corridors, open corridors with seating, or long thin office spaces.
  • For corridors longer than 28m, plan multiple units spaced along the length rather than one unit stretched beyond its rated footprint, since PIR detection along the long axis weakens well before the stated maximum length in practice.
Outdoor and Entrance areas
  • TECTA D280i WH and  TECTA D280i AN : 180° detection angle, Ø24m range, wall-mounted, ideal for open areas like car parks or building perimeters where long-range detection matters more than close-in sensitivity.
  • TECTA D180i WH and  TECTA D180i AN: 180° detection angle, 14m range, better suited to shorter approach distances such as front doors or side entrances.

Because both are wall-mounted at 180°, position them facing across likely pedestrian movement rather than directly at an approach path, since PIR sensors detect lateral movement across their field more reliably than movement heading straight toward them.

False Ceiling installations

The thePiccola P360-100 DE WH matches the PIRA T8’s Ø8m/50m² coverage but is built specifically to sit flush within a suspended ceiling void, making it the right choice over a PIRA T8 wherever the ceiling type itself is the deciding factor rather than room size.

Switch and Load-type Guidance

Standard lighting control (single relay)

Most detectors in this range, including the:

include one 230V relay channel rated for direct lighting control. This is the right choice whenever the detector only needs to switch lights on and off.

Combined lighting and HVAC control (dual relay)

Where the same sensor should also drive heating or ventilation based on occupancy, the PIRA T8-2 DE and LUXA 103 S360-101-12 AP WH  add a second, potential-free relay channel dedicated to HVAC equipment.

This avoids installing a separate occupancy sensor purely for climate control. Use these models specifically when a room’s heating or ventilation should follow occupancy the same way its lighting does, for example in meeting rooms or intermittently occupied offices where running HVAC constantly would waste energy.

Why Presence and Motion Detection Systems Matter?

Reduced Energy Use Through Automatic Control

Presence and motion detection helps lower energy consumption by switching lights and connected systems on only when spaces are occupied. Empty rooms are no longer lit unnecessarily, reducing wasted electricity. Automatic control works consistently throughout the day without user input. Over time, this leads to measurable energy savings and more efficient building operation.

Improved Comfort in Occupied Spaces

Lighting controlled by presence and motion detection systems responds immediately when someone enters a room. Presence detectors maintain operation even during periods of low movement, ensuring lights stay on while a space is in use. This removes the frustration of lights switching off unexpectedly. Occupants experience a more comfortable and reliable environment.

Enhanced Safety and Visibility

Automatically activated lighting improves visibility in stairwells, corridors, and entrances. Presence and motion detection systems ensures these areas are illuminated when movement is detected, reducing the risk of trips or accidents. This is especially important in shared or public spaces. Better lighting control supports a safer overall environment.

Flexible Solutions for Different Environments

Presence and motion detection systems can be applied across many settings, from private homes to large commercial buildings. Sensors can be adjusted for detection range, sensitivity, and time delays. This flexibility allows solutions to match how each space is used. Both simple installations and complex layouts benefit from adaptable detection control.

Reliable Performance with Minimal Maintenance

Modern presence detectors and motion sensors are designed for long-term reliability. Robust construction and proven detection technology ensure consistent performance over time. This reduces maintenance needs and system downtime. Reliable detection helps building systems operate as intended day after day.

Why Use a Square Detection Area Instead of a Circular One?

Our presence detectors feature a square detection area with a 360° field of view, making planning simple and effective – especially for square or rectangular rooms. This ensures seamless coverage without blind spots or overlaps, offering reliable detection throughout the entire space. Unlike circular detection zones, our square layout provides optimal room coverage with maximum precision.
