ATTENTION!
If the motion sensor is installed too close to the light source it switches, the system may activate, i.e. the sensor will spontaneously turn the light source on and off. It is necessary to move the sensor to an appropriate distance away from the light source it activates.
Operation
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-08 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 the range of 1 to 2 meters radius (for h=2.5-3.0 m) and the switching time of the receiver within the range of 3 s to 12 min. Changes in tempera-ture can affect the motion detection.
The motion sensor can work indoors and outdoors in places, where it is not directly exposed to rain or snow and where there is no risk of splashing the sensor casing and its electrical terminals with water or other liquid.
