5.2 Project Notes People Counter (GPC)
The radar sensor of the People Counter detect moving objects within the detection area / beam
(A1, A2, see Fig. 12) of the radar antenna. The size of the detection area, and hence the sensitivity
of the devices can be adjusted with jumpers JP1 and JP2
A door (including glass doors), a curtain and in particular automatic doors or other moving objects
can influence the counting of the People Counter much.
If a People Counter is installed in the antenna, the antenna conductors in the middle of the antenna
body must be aligned, that the red arrows show, according to
Fig. 8 Transverse conductors facing
in the direction of free space.
That means, the antennas are installed close to the entrance and exit, the detection area of the
radar sensors must show away from the door. Otherwise, a minimum distance of 1.0 m between
moving objects and detection areas must be guaranteed.
