Functioning
The sensor detects the infrared radiation sources. It analyzes the parameters such as the size of the object, the amount of heat emitted and the speed of movement between sectors of detection. Movement in the detection area 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. Another movement in the detection area and its subsequent disappearance during the measured time resets the support time to the beginning. The specific of operation allows to use the DR-07 as a presence sensor. The motion sensor is equipped with a twilight sensor to prevent switching the lighting on during the day. Detection status and standby to switch on the lighting are activated only after dark. The activation time of the sensor can be adjusted by the user with potentiometer. In addition, user can adjust the area of detection within a range of 1 to 4 meters radius (for h=2.5-3.5 m) and the switching time of the receiver within a range of 3 s to 9 min. Changes in temperature can affect the motion detection.
