The Elsys ERS2 Eye is a sensor that measures room occupancy. ERS2 Eye can be mounted on the ceiling or on the wall. It detects the presence of body heat in the room by measuring the temperature in an 8-matrix with a viewing angle of 60 degrees. This can be used for dynamic workplace management, facility management and workplace statistics. The sensor also measures temperature, humidity and light. The two necessary 3,6V AA Lithium Batterien are not included in the scope of delivery and must be ordered separately.
The ERS2 sensor from ELSYS measures the indoor climate and occupancy of indoor rooms and comes with various options depending on the version. All sensor versions in the ERS series have NFC (Near Field Communication) for easy communication with a smartphone.

PIR motion detector or ToF sensor
PIR motion detector
How a PIR motion detector works:
The PIR motion detectors (passive infrared sensors) are named after pyroelectricity, whereby a change in temperature leads to a measurable change in electrical voltage. Every living organism emits infrared radiation. A change in the heat source registers that something is moving and, depending on the design, in which direction it is moving. PIR motion detectors are therefore often used as light motion detectors, whereby the light is activated when a PIR motion detector registers movement.
Applications of a PIR motion detector:
PIR motion detectors are key instruments in smart facility management. They regulate the motion detector light in offices and public spaces, reduce energy waste and increase comfort. At the same time, they detect unauthorized access, contribute to security and enable efficient lighting control as part of smart facility management.
ToF sensors
How a ToF sensor works:
The ToF sensors are named after the term Time-of-Flight, which also describes exactly what happens with these IoT sensors. They measure the time it takes for the emitted light to be reflected and to arrive again. Depending on the model, several fields are used to register not only whether something is in the entire area, but also the differences within this area. This can be very helpful in applications such as offices or business premises where user behavior is also relevant. Together with learned patterns through AI, ToF sensors can be the basis for many intelligent applications.
Applications of a ToF sensor:
ToF sensors are valuable tools in smart facility management. They enable the precise recording of room utilization in offices and event rooms as well as people counting with directions of movement. As effective people counters, ToF sensors record the presence of people in real time and enable demand-oriented use of the premises as part of smart facility management.
