Detection and measurement

With MDT sensors, your smart home can react appropriately

Information for the KNX system

Automation only works with sensors

Building automation becomes smart when the system reacts appropriately to the current situation. When the sun is blazing, the sunshade moves down; if someone enters the hallway, the light gets brighter; if the building is cooling down, the heating is activated.

In order for this to work, the system needs to be provided with the relevant values by sensors. Then appropriate automatic reactions can be configured in the KNX system.

MDT Presence Detectors and MDT Motion Detectors

You can determine whether people are present or not with presence detectors and motion detectors. You can link actions, such as lighting in the storeroom or the comfort temperature in the living room, to presence. In this case, presence detectors are used in rooms where people spend extended periods.

The detectors have more refined detection and can therefore recognise even smaller movements, for example a person at a desk. For areas that are only used briefly (such as hallways or side rooms), motion detectors are used. They have a detection angle that prevents them from detecting small pets.

Values for your KNX system


MDT Sensors

Measuring sensors give values to your KNX system, which the system can use to control the home technology. A VOC sensor is installed to measure the air quality in the room. The measured values can either be displayed as red-yellow-green traffic light values in a visualisation, or you can have the ventilation switched on immediately from a particular threshold value. The humidity sensor is also interesting for ventilation. It is installed in the bathroom and its values are used to provide fresh air automatically after showering. In all rooms there is a temperature sensor, and its values are crucial for the heating control.

In passageways without motion detectors, it is advisable to use a brightness sensor that will provide values that will brighten an orientation light if there is not enough light. A weather station is installed for the outdoor area. This provides information about the wind speed, the outdoor temperature and the solar radiation. An additional sensor can also provide information about rain. These values are particularly relevant for controlling the sunshade, which can then be perfectly adjusted to the current weather situation.

CO2 / VOC Combi Sensor

Measures the air quality in the room and controls heating and ventilation

Room Temperature Controller

With adjustment knob to control the indoor temperature

Object Controller

Automatically controls the indoor room temperature

Room temperature/ humidity sensor

Measures the room temperature and the humidity

Really smart is when the air quality in the room is measured and the heating and ventilation are automatically controlled.

Die Beschattung: Perfektion ist, wenn sich die Lamellen der Jalousien anhand des Sonnenstandes selbst ausrichten.

The shading

Shade is really smart if it adjusts automatically to the current weather conditions. You need a precisely aligned system in order to achieve this.

Die Beleuchtung: Licht – immer wenn Du es brauchst und in der passenden Beleuchtungsstärke

The lighting

The right lighting has a huge influence on quality of life for the occupants. It provides comfort, security and energy efficiency.

Die Heizung: In jedem Raum die passende Temperatur zu jeder Tageszeit

The heating

Heating and cooling appropriate for the time of year and ambient temperature so that the rooms are always at the optimum comfort temperature.
