Presence Sensor
Item no.: presence-sensor

Presence Sensors are key communicators involved in any type of building automation project. With reliable detection of presence and motion, it forms the basis for the automation of important functions such as lighting (including maintaining constant light levels), burglar alarm, audio, HVAC, and much more:

  • 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 26ft detection field at a ceiling height of 9.8ft).
  • Integrated brightness sensor (measuring range 0 ... 83000lx)
  • 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

All-in-one sensing capabilities: motion, sound and brightness

All-in-one sensing capabilities: motion, sound and brightness

An upgrade from the classic Motion Sensor, the Presence Sensor takes on more forms of detection. For example, it is now possible to detect when a person is sitting still in front of the TV set because it is detecting not only movement, but also sound. Similarly, the possibilities of doorways blocking motion is no problem for a Presence Sensor. Thanks to the integrated multi-sensor technology, you can save on detectors in a typical project while helping your customer to save money.

Motion (via infrared)

With a detection angle of 360° horizontally and 110° vertically, the Presence Sensor detects movement within a radius of 26 ft (with a ceiling height of 9.8 ft). The sensitivity can be adjusted in four steps.


In addition to detecting movement, this can be extended by the acoustic sensor. The threshold value of the acoustic detection can be set via Loxone Config.


A high-quality brightness sensor with a wide detection range is well suited for the implementation of brightness-dependent functions such as constant light control.

Extending the reach with acoustics

The Presence Sensor offers a wide range of possibilities:

Automatic time-out feature

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 there is no detection of motion or audio 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).

Individual thresholds

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

How does sound detection work?

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

Presence detection for Ambient Assisted Living (AAL)

Especially when older family members live alone at home, it is important for relatives to be able to check up on them unobtrusively. For this reason, specific actions can be monitored by the Presence Sensor. For example, an alarm could be triggered based on fall detection, changes in behavior, or other specified emergency situations.

Installation and configuration

With the fiber-reinforced mounting bracket, the Presence Sensor Tree can be easily and securely mounted on either the ceiling or the wall. With the expertise of a Loxone Partner, Loxone Tree offers unparalleled ease of install through Loxone Config.

loxone tree

Award-winning Loxone Tree Technology was designed with a clear goal in mind: reduce wiring and installation effort required. Thanks to a free-form wiring topology and intuitive configuration software, Loxone Partners are able to have Loxone Tree devices up and running in record time.
