Motion sensor for detecting infrared radiation and surrounding brightness has a sensor assembly on a printed circuit board, a sensor element and a switching structure with a micro-controller
Motion sensor for detecting infrared radiation and surrounding brightness has a sensor assembly on a printed circuit board, a sensor element and a switching structure with a micro-controller
A switching structure (4) has an operational mode switch-over device (8) that relies on an adjusted value in a first adjusting element (5) for follow-up time and/or on an adjusted value in a second adjusting element (6) for minimum brightness for automatic adjustment in two different operating modes, i.e. a watchman or a presence sensor.
