As part of my MSc project I am measuring human activity on the stairwells in the MPEB, I’ve made some Arduino based people-counters which are now installed on the stairs.
When you move past the unit you may notice it lighting up red- don’t worry, this just means it’s working! I’m using this information as a baseline to compare stair usage between now and after my project has been installed.
If you want any additional information please feel free to write a comment or get in touch with me!
