Device is imposed on separate block for hidden conducting and mounted under a ceiling. Depending on movement and illumination degree the sensor turns on the light, and ventilation. Thanks to a corner of review of 360 degrees, this device works irreproachably, not dependent on from what point a person comes nearer. It is convenient not only from the point of view of visual perception, but also substantially saves energy consumption. Thanks to automatic switching-on/switching-off function, lighting is used only when it is really necessary. Situation, when light remains switched-on through an oversight, is excluded.
