8 Software and board package
The software example runs a proof of concept, implementing the algorithm as described above. This software
runs on a NUCLEO F401RE board, accompanied by one X-NUCLEO-53L1A1 expansion board (see figure
below).

To operate,
• Place the device without any object within 2 m in front of the ToF sensor
• Wave your arm in front of the sensor from left to right and from right to left at a distance ~50 cm
• the people counting result displays as shown in the figure below (in Tera term)
• The serial baud rate is set at the 460800 bauds per second
