Combine the sensitivity of microwave detection with the precision of PIR in one adaptable sensor—so lighting responds when it should, and stays off when it should not.
HF can detect fine movement across a wide area. PIR precisely identifies changes in body heat. Dual-Sense™ brings both together, giving designers and installers the freedom to choose the right detection logic for each project.
ONE SENSOR LOCATION · TWO DETECTION INPUTS
Concept diagram only. Detection geometry and maximum range depend on product, lens, mounting height and sensitivity settings. Always refer to the latest product datasheet.
Each technology excels in the right setting. Dual-Sense™ helps cover the conditions where a single sensing method can reach its limits.
Highly sensitive motion sensing with broad coverage and no direct line-of-sight requirement.
Stable, heat-based sensing that is ideal for clearly defined zones and privacy-conscious applications.
The goal is not to declare one technology better. It is to understand which environmental conditions can create unwanted triggers or missed detection.
HF waves can reflect from metallic surfaces and extend the detection pattern.
Fans, curtains or moving equipment may be interpreted as occupancy.
Signals may pass through lightweight materials into adjacent areas.
Strong sunlight and nearby heat sources can affect infrared contrast.
Furniture, partitions and glass can interrupt the line of sight.
Small movements in cold environments may create less infrared change.

Maximum sensitivity for fine movement and wide-area responsiveness.
Precise, heat-based sensing for controlled and clearly defined zones.
Triggered by HF or PIR to provide maximum coverage and responsiveness.
Triggered only after both sensors detect movement, reducing false activation.
Choose the adjustment method that suits the product, installation and level of control required.
Fast, reliable configuration directly on the sensor.
Adjust settings safely from floor level after installation.
Advanced wireless configuration from a smartphone or tablet.
Dual-Sense™ is most valuable where changing conditions make conventional single-technology detection difficult to tune.
Flexible detection logic helps accommodate tall mounting heights, long aisles and changing movement patterns.
HF can support occupancy detection where heat sources or changing temperatures reduce PIR contrast.
Adapt sensing behaviour as activities shift from intense movement to near stillness.
A sensor that can adapt to the space reduces the need to change hardware when layouts, activities or environmental conditions evolve.
Use confirmation from both technologies where environmental movement is present.
Change detection behaviour without replacing the sensor or rewiring the installation.
Select HF, PIR, either or both to suit the actual space rather than a fixed assumption.
Better matching of detection logic helps reduce occupant complaints and repeat visits.
If two or more of these conditions apply, combined sensing can provide useful commissioning flexibility.
