The “sweet spot” for detection is along a perpendicular axis to the planar antenna. Mount the mounting
plate such that the planar antenna can be adjusted so it is in a parallel plane to the desired visitor location
and so the perpendicular vector is centered on the desired target.
Adjustments:
Sensitivity Adjustment: This adjustment will determine how close the visitor needs to be to trigger the detector. Use
the potentiometer on the right side of the device to adjust this value. Counterclockwise increases the detection area;
clockwise reduces it. The potentiometer is right of the antenna in the lower right hand corner of the PCB (See Fig. 5).
See Fig. 6 for a typical detection range based on the device being mounted on a vertical surface (i.e., looking down)
at a height of 2.2 meters and with the planar antenna at a 30º angle.
