Hi everyone , i'm new to electronic engineering and i hope to build a system to count the approximate queuing people in the line .My idea is to use passive infrared sensor pairs. One install in the ceiling and one on the ground. With three or more pairs of sensor as the input which the system then can compute the approximate queuing people.
Is it possible to do it on arduino?
Furthermore, i wish that the data can display on the internet web .
Sorry for my poor english.
