Hello! I'm new in arduino and I have just done basic expiriments with leds etc. I'm planning to do a little project, the headpoint is to recognize if someone sitting in a chair for example fall asleep and then send out and alarm.
It will not be that advanced, my idea was that the first sign when someone fall asleep is the nodding. So I thought about using a tilt sensor perhaps placed on head somewhere which sends out an signal when the person nodd, then the alarm goes on. It should be really basic at the beginning then I might improve it. My question is, how many degrees counts as a tilt, and where should i place it on the head to get it work? (And is the tilt sensor the optimal choice)? Well I hope someone could help me.
