Presence detection is one of the most important input elements in building automation. If we know whether someone is in the building, it affects lighting, heating, security, ventilation, energy management and much more. Loxone's recessed presence sensor has a low profile for ceiling installation; it reliably detects motion and presence, as well as measures light intensity - making it an invaluable element of building automation.
The presence sensor developed for recessed ceiling installation fits perfectly flush with the Loxone LED Spots thanks to its flat design, thus ensuring a uniform appearance in the interior. It reliably detects motion and presence, measures light intensity, and forms the basis for many functions of Loxone home and building automation.
It is equipped with infrared (PIR) and acoustic sensors that reliably detect motion and sound. Thanks to the built-in light intensity sensor, constant light level regulation can be easily and quickly implemented. This function is particularly indispensable in the commercial sector, for example in large office buildings, warehouses, or other industrial facilities.
Multisensor technology: built-in infrared, acoustic and light sensor
A simple motion sensor does not detect if, for example, someone is just sitting at a table or in front of the TV without much activity. Various installation factors can also affect the effectiveness of a motion sensor, for example if it is obscured when a door is open. This is why the Presence Sensor Tree was created - to make presence detection more accurate in every usage environment, whether in residential or public buildings. The Presence Sensor can reduce device costs in unusual usage environments where several simple motion sensors would be needed.
| Motion | Presence | Light intensity |
| High detection range: field of view 360° horizontally and 110° vertically (in a circle with 8 meter diameter, 3 meter ceiling height). Sensitivity can be set to one of 4 different levels. | After the device detects presence based on motion, the presence factor can be further enhanced by sound detected by the acoustic sensor. The acoustic detection threshold can be set using Loxone Config. | The high-quality built-in light sensor (0 ... 83000lx) provides the best solution for functions based on light intensity, such as constant light level regulation or lighting adapted to natural light conditions. |
A versatile acoustic sensor
Thanks to the built-in acoustic sensor, the Presence Sensor can be used in an even wider range of applications.
| Automatic timeout extension | Intuitive reactivation | Custom thresholds |
| When motion is first detected, the Presence Sensor's audio sensor automatically extends the timeout - even if it detects no motion. | If no motion or sound is detected during the set period, then - for up to 10 seconds after the period - the presence sensor remains on standby in case of any possible sound to extend the time limit (for example, a clap). | When a certain noise level is exceeded (this can be set in Loxone Config), the Presence Sensor's alarm output activates. With this, various functions can be activated, such as notifications or alarm triggering. |
How does acoustic detection work?
The Presence Sensor contains an acoustic sensor that detects noise and measures volume, then transmits this value to the Miniserver.

Design and installation
Thanks to its flat design, the Recessed Presence Sensor Tree fits perfectly with the Loxone LED Spots, thus ensuring a uniform appearance. For ideal synergy, we recommend that the Presence Sensor be positioned in the center between two LED Spots, following the traditional grid layout.

Presence detection in elevated care situations
Especially when elderly or care-dependent people live alone at home, it is important that relatives know that everything is fine. Presence detection can help with this. Falls, behavioral changes and emergencies can be detected, which may even trigger an alert.
