IP20 motion sensor black DR-09B

Infrared motion sensorfor use in narrow corridors

With the function ofpresence sensor

Motion sensorallows forautomatic, temporary switching on of the lightin the event of a person or other object appearing in such places , such as: corridors, yards, approaches and driveways, garages, etc.
Motion sensorcan work indoors and outdoors. Outside only  in places where the sensor housing and its electrical connection points are not exposed to direct rain or snow or splashing with water or other liquid.

The infrared motion sensorworks by detecting movement of heat sources that are within its area of operation. Important elements affecting the detection efficiency are:

• the amount of heat emitted by the moving object and the ambient temperature,

• the size of the moving object ,

• direction and speed of movement.

Efficiency of the infrared motion sensor  will be the smallest when:

• the temperature of the moving object is close to the ambient temperature (e.g. a sunny room, a radiator in the detection field, etc.),

< li>

the object moves at a low speed directly towards themotion sensor,

• the size of the moving object will be small compared to area of the detection zone.

Examples of situations that may lead to incorrect operation of the infrared motion sensor:

< light sources located in the sensor's detection field. Turning the light on or off causes a large and quick change in the temperature of the bulb, which can be interpreted by theinfrared motion sensor as a moving object.
