IFS105SE
Round Indoor Sensor for LLLC
Compact Bluetooth luminaire sensor with PIR and daylight harvesting – turns standard luminaires into smart ones (2–5 m).
DetailsSolution
Lighting control that thinks ahead.
Light only where people are – and only as bright as needed. Our sensors combine presence detection, daylight harvesting, schedules and scenes into a single system that saves up to 92% of lighting energy.
Benefits
Why sensor-based lighting control?
Up to 92% savings
Combining presence detection, daylight and schedules significantly cuts electricity costs and CO₂ emissions.
No control cabling
Bluetooth Mesh connects sensors and luminaires wirelessly – ideal for retrofits too.
Fast commissioning
Configuration via app – profiles and schedules set up in minutes rather than days.
Fail-safe
The intelligence sits in every luminaire: if one node fails, the rest keep working.
Measurable
Energy monitoring per zone makes savings transparent and verifiable.
Open
Integration with the building management system (BMS) via BACnet, Modbus or API.
How it works
Four strategies, one system.
Real savings come from the interplay of several control strategies:
- Presence control – lights switch off or dim as soon as an area is vacated.
- Daylight harvesting – luminaires near windows dim automatically.
- Task tuning – installed output is capped at the level actually required.
- Schedules – base lighting and switch-off follow operating hours.

FAQ
Frequently asked questions
How much do sensors save – with and without an LED retrofit?
As a guide from our projects: switching from conventional lighting to LED with sensors reduces lighting electricity by up to 90 %. If LED is already installed, sensors alone typically save more than 60 %. Calculate your figures with the savings calculator.
What is the difference between a presence detector and a motion detector?
Motion detectors respond to larger movements and usually just switch lights on and off. Presence detectors also pick up fine movements – such as someone working at a desk – and usually add daylight-dependent control. Find out more in our guide.
How quickly does lighting control pay for itself?
That depends on operating hours, electricity price and your starting point. Use the savings calculator to estimate your payback period.
Does the control system also work with existing luminaires?
In many cases, yes: with the Bluetooth node FA102 and battery-powered sensors, existing dimmable luminaires can be retrofitted.
