5. USB/UART Normal Operation
5.1.
Operation of the TeraRanger Evo People Counter
sensor module
The TeraRanger Evo People Counter counts people passing by.
The output of the sensor is:
●
A sensor ID, to allow the identification of the sensor when part of a multi-sensor
installation
●
A meter counting the difference between In and Out
●
A meter counting the number of people passing by, from left to right (In)
●
A meter counting the number of people passing by, from right to left (Out)
The sensor should be installed with the USB/UART Connector placed on the right side,
as shown in figure 9.

The detection range of this mode can be adjusted from a minimum of 0.05 m to a
maximum of 1.7 m. To detect a person passing the set detection range has to be
breached.
