Motion detector in the house


Motion detectors do not necessarily have to be used outdoors, ie outside. You can also use motion detectors in the house. What you should consider when using motion detectors in the house, we have discussed below for you.

Possible applications of motion detectors in the house

Motion detectors are used to switch an electrical load without manual operation, for example, a light switch. Especially in the house there are numerous possibilities to switch a motion detector:

  • Bathroom and toilet
  • Hallway, hallway
  • stairwell
  • storerooms
  • garages
  • alarm systems

All these areas are predestined to be switched with a motion detector. Especially in households, where it is often "forgotten" to turn off the light again, profits to a great extent by significant energy savings.

Use motion detectors in the house - you should pay attention

Make consumers additionally switchable

However, there are also some special features to consider. Especially in the house, it may well be necessary that either the light manually and permanently switched on or off accordingly. Therefore, always appropriate light switches should be integrated into the installation, which can control the motion detector accordingly.

You will find the corresponding guides and instructions in the house journal under "Switching off the motion detector" (switching off the light permanently without being influenced by the motion detector) and under "Switching the motion detector" (permanently switching on the light without being influenced by the motion detector).

The functioning of the detectors used

But also the type of motion detector used is important. The most frequently used motion detectors are PIR detectors (infrared motion detectors), HF motion detectors (high-frequency motion detectors) and photocells (also photoelectric sensors). By far the dominant detectors are PIR motion detectors, ie devices controlled by infrared.

Like photocells, these require direct contact with the surveillance area, so they must not be obstructed by any objects. The triggering works with these motion detectors by means of temperature differences, which perceives the infrared radiation. In contrast, HF motion detectors can also be installed behind stems or even behind walls and in ceilings (eg suspended or drywall ceilings). They are not visible and still capture all movements in the defined area.

Any additional functions required for use in the house

In certain situations, for example in a staircase circuit with additional switches and a time control device, a supplementary motion detector must have additional functions. These are motion detectors with impulse function. But even the relevant control unit must be controlled accordingly.

Tips & Tricks

In the house journal, we also offer you guides that help you professionally connect a motion detector. With the search function you will find many more topics about motion detectors.
