## Summary description

Steinel TRUE PRESENCE COM1 DE is a presence and dusk sensor designed to detect human movement and ambient light changes. The unit monitors presence for precise motion detection and measures dusk levels to control lighting. It is suitable for indoor installations where automated lighting control and energy saving are needed, supporting integration with lighting systems.

## Long description

Steinel TRUE PRESENCE COM1 DE is a presence and dusk sensor engineered for indoor lighting control. The device monitors human presence using advanced detection logic and simultaneously measures ambient light (dusk) to determine lighting needs. Designed for integration with building and lighting control systems, this unit enables precise switching and dimming based on occupancy and natural light levels, supporting energy-efficient operation in offices, corridors, meeting rooms and other interior spaces.
Advantages
The sensor combines presence detection and dusk measurement in a single compact housing, allowing continuous monitoring for both movement and ambient light without separate devices. Its presence detection logic distinguishes between short movements and sustained occupancy, improving reliability for automatic lighting control. The dusk measurement function helps avoid unnecessary switching when sufficient daylight is present, which reduces energy consumption. The design supports straightforward installation and integration into lighting systems, offering consistent performance for indoor applications.
Suitable for
 Offices and open-plan workspaces
 Corridors, stairwells and lobbies
 Meeting and conference rooms
 Interior retrofit projects and new installations with automated lighting
Key specifications
 Detection type: presence (movement and occupancy monitoring) and ambient light (dusk) measurement
 Installation location: indoor mounting suitable for ceilings or walls depending on system integration
 Integration: designed for connection to lighting control systems for switching and dimming
 Operational focus: continuous presence monitoring for precise lighting control and energy efficiency
 Physical characteristics: compact sensor housing for unobtrusive placement in interior spaces
How to use
Install the Steinel TRUE PRESENCE COM1 DE according to the electrical and mounting requirements of the lighting control system you are using. Position the sensor to cover the intended detection area so that presence and ambient light are reliably monitored; avoid mounting locations with direct exposure to heat sources or reflective surfaces that can affect detection. Configure the sensor’s presence and dusk thresholds via the connected control system or device interface, and verify coverage by testing occupancy detection and automatic lighting responses under different ambient light conditions.
Usage recommendations
For optimal performance, locate the sensor centrally to the monitored area and calibrate dusk threshold levels to local daylight conditions. Use the presence detection for spaces where intermittent occupancy is expected and combine with time-based schedules in the lighting control system to further enhance energy savings.
