Presence detectors offer a high level of comfort by automatically controlling lights and systems. Brightness-controlled switching ensures that light is only switched on when needed. Even the smallest movements, such as typing on a keyboard, are detected to prevent unnecessary switching off. As soon as the room is vacated, the light and connected systems switch off automatically. This saves energy and increases comfort – everything works automatically, without manual intervention.

Presence detectors have long since ceased to be limited to detecting presence. Thanks to advanced multisensory technology, they can capture up to nine different sensor values, opening up new possibilities for intelligent building control. This data collection makes it possible to optimally adapt the indoor climate to the needs of people while maximising energy efficiency. The multi-sensor system not only makes buildings more intelligent, but also sustainably improves the well-being of the users.

STEINEL presence detectors are not only designed to meet today's needs, but also to meet future requirements. By using proven interfaces such as KNX and DALI, we ensure reliable integration into existing building control systems. At the same time, we are focusing on modern IP interfaces and Bluetooth mesh. This means that our products can be easily integrated into current and future IoT solutions and offer maximum flexibility for the requirements of tomorrow's digital building world.

Presence detectors in hotels increase comfort while reducing energy consumption. They detect whether guests are in the room and automatically control the lighting, heating and air conditioning. If the room is empty, these systems are shut down. Housekeeping also benefits, as it is immediately apparent whether a room can be cleaned. In corridors and public areas, the sensors only switch the light on when needed, which saves costs and energy.

Presence detectors automatically control lighting, heating and ventilation in offices. They detect whether employees are present and only switch the systems on when needed. If the office is empty, they are switched off, which reduces energy consumption. By detecting the smallest movements, such as typing on the keyboard, presence detectors prevent unnecessary shutdowns and ensure a pleasant working environment. This increases comfort and supports sustainable use.

In the field of education, presence detectors play an important role in creating a pleasant and efficient learning environment. In classrooms or lecture theatres in particular, they automatically adjust the lighting to the available daylight. This means that only as much artificial light as is really necessary is used. Thanks to this daylight-dependent control, the room is always optimally illuminated without consuming unnecessary energy.

In apartment buildings, presence detectors are used in corridors, stairwells, underground car parks and communal rooms. They only switch the light on when it is needed, which reduces energy consumption and increases safety. The sensors also provide reliable detection in corners that are difficult to see. This ensures that rooms and paths are efficiently illuminated as soon as people or vehicles arrive, significantly increasing residents' comfort.

In garages, warehouses, driveways or courtyards, sensors are needed that can detect large radii. They also have to work reliably in damp and cold weather. This makes passive infrared (PIR) technology the technology of choice here. It detects the heat radiated by people and converts it into a measurable electrical signal. And because we at STEINEL want to offer the very best solution, we have further developed this technology to such an extent that our IR sensors provide the best detection quality on the market.

Based on the Doppler principle, an active high-tech sensor emits signals that can easily penetrate glass, wood and lightweight walls and be sent back as an echo. If this echo image changes due to movement within the detection range, the sensor detects this and switches on the light in fractions of a second. High-frequency detectors are the right choice when it comes to providing seamless coverage in the most demanding of applications, such as schools, airports, administrative and office buildings, and complex areas.

The ultrasonic waves are actively emitted by the sensor and propagate fully in the respective room. They fill the room to the last corner and enclose objects that are in the room. The sensor detects motion in the room, even if there is no visual contact between the sensor and the person. This makes ultrasonic sensors perfect for open-plan offices and rooms with lightweight construction. Ultrasound does not penetrate thin walls and is very sensitive. And that is precisely why it is recommended for rooms in which sedentary work is carried out.

Our True Presence® technology is based on the finest high-frequency measurements of the environment. The presence of people is indicated when three-dimensional breathing patterns (micro-movements of vital functions) are detected. The combination of an extremely sensitive antenna and unique sensor software ensures that the presence of people is detected 100%. And it does so so quickly and accurately that there is no need for a switch-off delay. The True Presence® product family offers revolutionary technology and is easily controllable via an app using Bluetooth.
