Note:
The detection range of the sensor is related to the moving speed and size of moving object, mounting height,
installation height and angle, installation site, reflectors around the sensor etc. The data in the document is
typical value and tested by a 165cm person in an open indoor area.
The detection range at wall mounting will be longer at ceiling mounting. Please reduce detection sensitivity at
wall mounting or contact us to confirm the sensor data settings.

12. Application Notice
1) The sensor should be installed by a professional electrician. Please disconnect the power before
installing, wiring or changing the setting of the DIP switch.
2) Sensor’s microwave can penetrate wall of building. It may cause misreport when microwave
penetrates wall to detect the moving objects outside fortified area. To avoid triggering by mistake,
choose suitable place when installing, keep away from glass, plasterboard, wooden wall and other
things that microwave can easily penetrate and choose appropriate sensing parameters according to
space, for examples:
A. When product is used in the room whose length and width is about 2m or less, detecting area should
be set to 25% (application scenario: washroom, sitting room )
B. When product is used in the room whose length and width is about 3m, detecting area should be set
to 50% (application scenario: washroom, hallway, sitting room )
C. When product is used in the room whose length and width is about 4m, detecting area should be set
to 75% (application scenario: small office, meeting room, library )
D. When product is used in the room whose length and width is about 5m or more, detecting area should
be set to 100% (application scenario: large office, meeting room, library )
Note: The setting detecting area depends on the actual environment (detecting area parameters above
application scenario are for reference only).
