Hi all, so this is a call for help on a school project.
The general idea is to give a certain amount of people entering a building a bracelet which will detect if there is another bracelet in a 6 feet perimeter and will be able to be detected from others as well.
I have certain questions;
- Are we able to have arduino as a server and hand the "lab rats" just the detectors and the thing to be detected? The idea behind it to connect them in a WIFI (I guess) to work and send the data back
- What parts do i need to use? I googled it and apparently Inductive Proximity Sensor are not good enough because they only detect metal.
I am happy to hear everyone's advice and thanks for your time in advance
