Infrared motion sensor DR-09

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. The sensor detects axis movement and own radius. 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 disappear-ance during the measured time resets the support time to the beginning. The specific of operation allows to use the DR-09 as a presence sensor. Detection area parameters: for presence up to 6 m diameter, and for motion range up to 20 m diameter. 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. In addition, user can adjust  the switching time of the receiver within a range of 10 sec to 30 min.
Changes in temperature can affect the motion detection.
The motion sensor can work indoors and outdoors in places 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.
