Infrared motion sensor DR-04 W white

Functioning
The sensor detects infrared radiation. It analyzes parameters such as: size of the object, the amount of emitted heat and the speed of movement between sectors of detection. Motion in the detection field will automatically switch on the lighting. From this moment the light will stay on, as long as the sensor detects continuous movement. Only the lack of movement in the detection area triggers the lighting support time. If the motion reappears in the detection field and disappears during the support time, it will trigger the sustaining time from the beginning. Nature of operation allows for using the DR-04 as a presence sensor. The motion sensor is equipped with a twilight sensor that prevents activation of the controlled lighting during the day. Detection status and readiness for switching the lighting are activated only after sunset. The activation time of the sensor can be adjusted by the user with potentiometer. Additionally, you can adjust the time period of the receiver switching in the range of 10 s÷15 min. Temperature changes can affect motion detection.
