Motion detectors & sensors

Intelligent lighting control for greater convenience and safety Motion detectors and sensors ensure needs-based and energy-efficient lighting. They are ideal for indoor and outdoor areas so that light is only switched on when it is really needed. However, the term “motion detector” is not entirely accurate. In fact, these sensors do not detect movements directly, but changes in their surroundings - whether due to temperature differences, electromagnetic waves or lighting conditions.

Master carpenter from Wiesbaden

Had to replace a lamp, but the same was no longer available. Great advice, found a suitable replacement and delivered it quickly.

What types of sensors are there?

The different types of sensors work according to different principles:

PIR sensors (passive infrared sensors): These detect temperature changes in their detection area caused by moving people or animals. They are particularly suitable for indoor and protected outdoor areas.
HF sensors (high-frequency sensors): These work with electromagnetic waves and react to even the smallest movements, even through thin walls or glass. Ideal for corridors, stairwells or offices.
Twilight switches: These do not react to movement, but to the ambient brightness. They ensure that light is only switched on and off again at a certain level of darkness.

Ultrasonic sensors: Work with sound waves and are best suited for indoor use.
Camera motion detectors: Work by electronically analyzing image data and are suitable for outdoor and indoor use.
Combined sensors: Many modern sensors combine several technologies to provide more precise results and avoid false triggers.

Advantages of motion detectors and sensors

Convenience: Switching lights manually is a thing of the past! Especially if the light switch is not immediately accessible (large halls, long corridors, outdoor areas) or if your hands are simply full, a motion detector makes your life much easier.
Efficiency: motion detectors only switch your light sources on when necessary. This saves both energy and costs.
Safety: With bright, automatic lighting, you can ensure safe paths and driveways around your application or property. Although light attracts mosquitoes, it deters unwanted guests. Sensor-controlled alarm systems also provide optimum security for your home or business. There are models that sound a signal or use light to make movement visible

The right detection area

The detection area of a sensor determines where and how reliably movements or changes are detected.

Indoors: In living rooms or corridors, the sensor should be strategically positioned so that it can detect movements at an optimum angle.
Outdoors: Here, the sensor type and positioning should be chosen to minimize unnecessary switching caused by wind movements or small animals.
Detection angle: Motion detectors are available with different detection angles, e.g. 180° for walls or 360° for ceiling mounting.

Additional setting options

Modern motion detectors offer numerous configuration options:

Sensitivity: Determines how strong a movement must be to trigger the sensor. - Light duration: Sets how long the light remains switched on after the last detected movement.
Twilight threshold: Determines the ambient brightness at which the sensor is activated.
Range: Depending on the model, the range can be adjusted to adapt the detection zone specifically.
