QBITSTRV1 controller is used for dynamic color (white) lighting of the stairs. The backlight is switched on with the controller subsequent steps, depending on the motion directions: ascending or descending The controller is adapted to control the WHITE LED strips arranged in stair steps and possibly the staircase handrails. Lights can be turned on by pressing Automatic, connected to the controller or by the use of additional sensor (motion) to detect when the person steps on the stairs. The controller is designed specifically for use with miniature motion sensors. It can be directly connected to the inputs of the controller without additional matching components. The controller can be operated with low voltage motion sensors or motion detectors for 5V-DC only.
