Introduction
This user manual explains how to use a VL53L1X long-distance ranging Time-of-Flight (ToF) sensor to count people crossing a
specific predefined area, like a meeting room entrance or a particular location in a corridor. It also describes an algorithm used
to count the people. The algorithm is provided as an example and can be downloaded from st.com, in the VL53L1X embedded
SW section, under the reference STSW-IMG010.
In addition, this document presents the details of a counting application where a sensor is set on the top, not the side, of the
area to be tracked.
