The KNX range from STEINEL
STEINEL KNX sensors are the "sensory organs" of modern building automation.
We are not only partners with KNX, but also with planners, architects and installers. We seek dialogue with them for suggestions and information from the field. Our service offers a comprehensive portfolio, from planning assistance, data provision and answering daily questions. See for yourself how good our sensors and technologies are. With our new system components and actuators, you get everything from a single source.

presence detector

Presence detectors are used wherever precise presence detection is required, such as in offices, conference rooms, schools and public buildings. They control lighting, air conditioning and other systems to save energy and increase comfort. Integrated into building management systems, they are an integral part of these systems and contribute to automation and efficiency.

motion sensors

Motion sensors are used in many areas. In home automation, they are used to control lighting, heating or ventilation, thereby saving energy. In public spaces, motion sensors help to illuminate paths and buildings, thus improving safety and comfort.

Smart Space Sensors

Smart space sensors continuously analyse the situation and provide information such as the number of people and occupancy of meeting rooms. This way, rooms and areas can be optimised for future use and, at the same time, the building management systems adjust the lighting, heating, ventilation and air conditioning.

system components

With the introduction of our new KNX system components, we now cover the entire range from sensors to power supplies, couplers, switch/blind actuators, dimmer actuators and DALI gateways. These components form the backbone of any KNX system and make it possible to address the individual requirements and needs of a building.

The next big thing.
EO sensor. Transforms rooms into intelligent rooms.

Work in progress. Before the end of this year, the new EO sensor will answer fundamental questions about building and space utilisation. To do this, it relies entirely on infrared technology for the analysis, thus ensuring maximum privacy protection. EO enables data-driven optimisations in various industries and sectors. In retail, for example, customer movements can be used for sales analysis, while in airports, office buildings, schools and production facilities, the sensor enables smarter building control in terms of health, safety and the environment.

Our sensor technologies

There are millions of successful KNX installations in Europe and around the world. STEINEL provides the "sensory organs" for KNX with the world's largest range of sensors. The sensor technologies we offer – passive infrared, high-frequency, ultrasonic and camera sensor systems – are used in many highly functional sensor variants. This means that you will find the right sensor for every application at STEINEL.

Passive infrared
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.

High frequency
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.

Ultrasound
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.

Optical sensor
Human Presence Detection (HPD) technology from STEINEL sets new standards in detecting people. It not only detects their presence but also precisely counts the number of people in the room. This makes it possible to optimise work areas, safety zones and building management in a targeted manner. Whether in offices, hotels, stores or public buildings – HPD technology makes it possible to control workflows efficiently and use resources optimally. Trust in STEINEL's innovative sensor technology to make buildings safer and more intelligent.

TruePresence®
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.
