Iam new to proximity applications with Arduino. I need to figure out a persons position in a rather small room (2,5m *1,5m).
Can you give me some advice on which sensors I could use? So the goal is to approximate where the person stands in that room with a presition of +-5cm. Dependent of the position arduino is going to trigger different actions. I also would like to calculate the direction and the speed of the person... (How quick can he be.. its only a small room)
I though about using 4 ultra-sonic sensors in all for corners of the room to calculate the position. Is that a realistic option? A problem that I could think of with that method is interference of the sensors? And also the question what happens if more people are in the room...
Thanks so much for your Ideas!
