You are sitting quietly at your desk, reading a report. You have barely moved for several minutes. Then the lights switch off. The room thinks you have left.
This familiar problem shows the difference between detecting movement and detecting actual occupancy. A true presence sensor addresses this gap. Sensinova SINO PRO uses 24 GHz radar technology to sense very small human movements, including breathing-related chest movement. The result is lighting that responds to whether someone is still present, not only whether they are walking around.
Traditional motion sensing works very well in spaces where people move regularly. Corridors, staircases and passage areas are good examples.
A different detection level is useful in rooms where people stay seated for long periods.
SINO PRO uses a 24 GHz radar system for true presence detection. The sensor reads tiny changes created by the human body. Within its close detection zone, even breathing can provide enough movement for the system to recognise continued occupancy.
So a person does not need to wave an arm just to keep the lights on.
Breathing causes small chest movements. They are easy to overlook, but radar-based sensing can recognise these subtle changes.
SINO PRO is designed to detect breathing within approximately 4 metres under suitable conditions. Its wider adjustable sensing range extends from 2 to 8 metres for presence and movement detection. When correctly installed, the sensor provides 360-degree coverage.
This creates two practical benefits. Occupants get consistent lighting during quiet activities. The lighting system gets better information about whether the space remains occupied.
In the inner area, extending to about 3 metres, the 24 GHz true-presence sensing layer detects very small movements made by a person who is seated or reading and helps maintain the occupied status. In the outer area, between 3 and 8 metres, standard motion detection detects walking activity over a broader room or corridor.
The control panel has additional adjustment controls. The LUX control determines the ambient light threshold, ranging from 3 to 2000 lux, and includes a SUN mode for operation regardless of daylight conditions. TIME1 and TIME2 establish separate switch-off delays for each channel, with settings from 10 seconds to 60 minutes. Channel 2 also provides an impulse mode for pulsed control signals.

Accurate sensing is only part of useful lighting automation. The sensor must suit the room and how it’s used daily. SINO PRO provides adjustable sensitivity across its 2 to 8 metre detection range. This lets installers set a focused detection area for a smaller room or increase coverage for a larger space.
Its adjustable ambient light setting ranges from below 3 to 2000 LUX. Lighting responds to surrounding brightness instead of activating unnecessarily in a well-lit room. You can set the time delay from 10 seconds to 12 minutes. Fresh detection restarts the timer. This keeps the light on during occupancy and switches off after the room becomes vacant.
A genuine presence sensor must never confuse stillness with absence; SINO PRO eliminates this problem with a two-stage detection method, suitable for offices, libraries, hotel rooms, and any area where people sit quietly for long periods. Sensinova designs each sensor in this range with installers and building owners in mind, aiming to reduce unnecessary shut-offs and provide lighting that reacts to presence rather than just movement.
If you have the next automation project in mind and need a genuine presence sensor that can tell the difference between empty and still, contact Sensinova about the SINO PRO. You can reach us at www.sensinova.in or email info@sensinova.in to include true presence detection in your build.
Fitting the ceiling mount in the middle of a room provides the broadest and most even coverage. The biggest gains are in offices, libraries, hotel rooms, and healthcare areas, where people often remain seated for long periods.
Motion detection focuses on physical movement. True presence detection can recognise much smaller human activity. SINO PRO uses 24 GHz radar sensing to recognise subtle movement, including breathing-related motion, during quiet occupancy.
Yes. Because it tracks breathing-based micro-movement, SINO PRO avoids the nuisance shut-offs common with standard motion sensors, keeping lights active for as long as a person remains present.
