Motion sensors with light control

Light control

— a function mainly used in light sensors.

Usually, such devices are equipped with photocells that evaluate the level of ambient light; if it is too light around and there is no need to turn on the lighting, the sensor simply will not respond to “external stimuli”. And adjusting the illumination allows you to adjust the response threshold of the photocell — that is, the level of illumination below which the sensor begins to work for its main purpose.
