sensor

A sensor in the light area serves to identify movement, the presence or presence of a person and/or to measure the brightness of the daylight or artificial lighting. In the event of a change, the sensor forwards this to the light management system, which then leads to the adaptation of light. Such an adaptation can either mean the pure out or switch on a lamp or the lamp is dimmed on the basis of it.

A light sensor that serves to measure brightness is ultimately an electronic component that converts light into an electronic signal using the photoelectric effect. A certain light intensity is assigned to the sensor, which it should perceive and then the light is to be changed, for example if dawn uses outside. This type of sensor is mostly used outdoors, for example, for twilight sensors, but also indoors for constant light control. In such light sensors, a distinction is then made between internal look-down or look-out sensors and external daylight measuring heads.

In the case of movement or presence detectors, the sensor does not measure the brightness, but captures movements in the area. This works using passive infrared sensors (abbreviated with PIR) or with high frequency sensors (abbreviated with HF). These sensors are then also used, especially in the outdoor area, for example, for example, for example, so that the light is directly concerned when arriving at home and you can find the keyhole without searching. How long the lamp should then shine is controlled by a timer and can be determined individually.
