Microwave motion sensor for flush mounting, with presence detector function

The sensor detects sources of infrared radiation.It analyzes parameters such as the size of the object, the amount of heat emitted and the speed of movement between individual detection sectors.Movement in the detection field automatically turns on the lighting.From the moment of switching on, continuous movement causes permanent switching on of the lighting.Only the lack of movement in the detection field triggers the lighting sustaining time.Another movement in the detection field and its disappearance during the countdown will trigger the backup time from the beginning.The nature of its operation allows the DR-03 to be used as a presence detector.The motion sensor is equipped with a twilight switch that prevents switching on the controlled lighting during the day.The detection status and the readiness to switch on the lighting are activated only after dusk.The sensor activation time can be adjusted by the user with a potentiometer.Additionally, it is possible to adjust the receiver activation time in the range of 10 s ÷ 7 min.Temperature changes can affect motion detection.The motion sensor can work indoors and outdoors in places where it is not exposed to direct rain or snowfall, and where it is not exposed to water or other liquid splashing around the sensor housing and its electrical connection points.The microwave sensor allows motion detection through wooden boards, plasterboards, glass and plastics.
