A Yugen sensor allows to detect presence and localize people. It is ceiling-mounted and extremely discrete.

A Yugen sensor is not bogger than a 1 EURO coin

The Yugen Controlling boards are necessary to control up to 32 wired and 32 wireless sensors and implement any additional functionality such as aggregation of sensors as well it supports a growing number of industry standard protocols such as ModBus and MQTT.

A single Xetal Yugen can be used to detect presence and monitor the surroundings of small areas such as a cash dispenser in order to understand if a person is present and when he/she is getting approached indicating a possible dangerous event

Yugen sensors can be used to monitor open spaces like in airports or train stations where counting of people and monitoring their flow is an essential element to improving safety, security and quality of service. The Y9090HH181 sensor with its coverage of above 40 sqm makes also installation and maintenance of Yugen solutions simple and cost effective.

Xetal Yugen technology can be used to detect one or more persons and know their position in order to understand who the person might be and what he/she is doing.

Xetal Yugen sensors can be used to measure a real-time thermal mapping of an entire area with high thermal and spatial accuracy.

Xetal Yugen Technology

Build from our experience with the Kinsei Technology, a Yugen sensor is capable to detect in real-time presence and provide the position of three or more persons for areas easily up to 7m by 7m. This information allows to implements systems that need to detect occupancy, to know the number of people and/or to monitor the flow of people in a given area.


A Yugen System uses temperature sensors (not to be confused with motion sensors) mounted on the ceiling. Each sensor does not rely on the movement of a person, but on the temperature itself, and it is connected by wire (or via a wireless adapter) to a control board. The control board that collects and transforms the temperature data into the detection information. The most advanced Yugen sensor can provide directly positional information without the need for a control board, simplify deploying in applications such as retailing and smart office.

Yugen is suitable for safety, security and any smart building application from small closed spaces to open spaces thanks to its simplicity in installation and maintenance.

The Yugen sensor family is composed by three type of sensors:

  • small area sensors: Their small viewing angle (10x40 degrees) makes them suitable for small areas like cash-dispensers, toilet cubicles, small lifts and office cubicles. Each sensor monitors the spaces as divided in three adjacent zones and indicates if a given zone is occupied or not. 

  • medium area sensors: They are suitable also for areas like small meeting rooms, cash-points, lifts and doors with a viewing angle up to 47x47 degrees. 

  • large area sensors: They are suitable for most closed and open areas. They have the capability to detect and localize one or more persons also without the control board. They can be delivered with viewing angles up to 105x105 degrees.
