Flush-mounted Presence Sensor Tree White

When it comes to building automation, the detection of presence is one of the most important inputs. Knowing if someone is in the building affects the lighting, heating, security, ventilation, energy management and more. The Flush-mounted Presence Sensor from Loxone features a low-profile for in-ceiling installation; reliably detecting motion and presence, and measuring brightness levels – making it an invaluable component for building automation.

  • Detect movement and presence through infrared and acoustic sensors
  • High detection field with a detection angle of 360? horizontal and 110? vertical (giving you an 8m detection field at a ceiling height of 3m).
  • Integrated brightness sensor (measuring range 0 … 32000lx)
  • Individually adjustable acoustic sensor threshold value for presence detection.
  • Individually adjustable acoustic sensor threshold value for the burglar alarm.
  • Simple limitation of the detection range using a sticker for the Fresnel lens



Unique multi-sensor capability: Infrared, Acoustic, and Brightness
A traditional motion sensor does not detect when a person is sitting e.g. at a desk or in front of the TV set and is not moving. Installation factors might also affect the effectiveness of a motion sensor, such as it being hindered when a door is ajar. This is why we developed the Loxone Presence Sensor ? to reliably detect presence more in more installation environments. With built-in multi-sensor technology, you can reduce hardware costs in non-traditionally shaped rooms that would have required multiple motion sensors.

High detection field with a detection angle of 360? horizontal and 110? vertical (giving you an 8m detection field at a ceiling height of 3m). The sensitivity can be set to one of 4 different values.

Once presence has been detected by motion, then the presence factor can be extended by sound detected by the acoustic sensor. The threshold value of the acoustic detection can be set via Loxone Config.

A high-quality brightness sensor (measuring 0 ? 83000lx) is perfectly suited for the implementation of brightness-dependent functions such as constant light levels and Daylight Responsive Lighting.

Versatile Acoustic Sensor
With the built-in acoustic sensor, the Flush-Mounted Presence Sensor Tree offers an even wider range of possible applications.

Automatic Time-Out Extension
With motion initially being detected, the audio sensor within the Presence Sensor can then extend the time out automatically ? even if no motion is detected.

Intuitive Reactivation
If neither motion nor audio has been detected within the preset period, then ? for up to 10 seconds after this period ? the Presence Sensor will still listen out for any audio to extend the time-out (for example, a clap)..

Customisable Thresholds
If a certain noise level is exceeded (adjustable in Loxone Config), the alarm output of the Presence Sensor is activated. With this, you can realise different functions such as triggering a notification or an alarm.

How the acoustic detection works
The Presence Sensor is equipped with an acoustic sensor that detects noises and measures the volume level. The volume level is then transmitted to the Miniserver.

Planning & Installation
With a low-profile design, the Flush-mounted Presence Sensor Tree complements the Loxone LED Spot to bring a cohesive look to your installation. To achieve a cohesive look, we recommend that you position the presence sensor centrally between two LED Spots, while following the conventional grid formation for the layout of the spots.

Presence Detection for Ambient Assisted Living
Especially when older people live alone at home, it is important for relatives to know that everything is in order. This can be achieved with presence detection as a form of unobtrusive monitoring. For example, an alarm could be triggered based on fall detection, changes in behaviour, or other such emergency situations.
