Features 1,The SINCELIGHT LED light equiped with PIR sensor,it is a kind of pyroelectric infrared sensors that detect variations in infrared rays.However,detection may not be successful in the following cases: lack of movement or no temperature change in the heat source.they could also detect the presence of heat sources other than a buman body.Efficiency and reliability of the system may vary depending on the actural operating conditions 2,Detecting heat sources other than the human body,such as: Small animals entering the detecting area. When a heat source,for example sun light,incandescent lamp,car healights etc., or strong light beam hit the sensor regardless whether the detection area is inside or outside Sudden temperature change inside or around the detection area causedby hot or cold wind from Heating,Ventilation and Air Condioning,or vapor from a humidifier,ect. 3,Difficulty in sensing the heat source: Glass,acrylic or similar materials standing between the target and the sensor may not allow a correct transmission of infrared rays. Non-movemnet or quick movements of the heat source inside the detection area. 4,Expansion of the detection area In case of a considerable difference in the ambient temperature and the human body temperature,the detection area many be larger than the configured detection area. 5,Dedection distance: The PIR motion sensor could detect variations in infrared rays however such variations are decided by following three factors.the temperature difference between the target and the surroundings:The large the temperature difference,the easier it is to detect targets. Movemnet speed:if the target is moving at a slower or faster speed than specified in the tables,the detection ability may be lower. Target size:Thehuman body is the standard,if the target is smaller or larger than specified in the table,the detection ability may be lower.The detection distance explained in our data sheetis defined by the three factors mentioned above.SINCELIGHT's standard for the temperature difference betewwn the target and the surrounding is defined as 4C.The larger the temerature difference,the longer the detection distance.if the temperature difference is 8Cwhich is twice as much as the standard.The detectuon distance will be approx.14times longer than the distance at 4C.For example,if targets ata a distance of 5m can be detected at 4Cthen the sensor can detect targets at a distance of 7m at 8CThis is based on the theory that the detection sensitivity will vary inversely with the square of the distance.)
