The idea for my project is to create an algorithm that will take information from 4 PIR sensors placed in every corner of a rectangular area. This data will be converted into coordinates by the use of an algorithm (any ideas?). The idea is to then use a DMX shield for the Arduino to connect it to a moving head light fixture , and translate the coordinates somehow into DMX language, controlling the pan and tilt of the moving head. This way a the light will follow the person.
my questions are:
- what kind of PIR sensors would you recommend? From my understanding, the measuring angle has to be at least 90 degrees and they have to be able to detect a person up to 4 or 5 metres.
-How would you assign the pan/tilt to the output of the sensors? Imagine the area that is made by the sensors to be a 2 dimensional rectangle on the x and y axises of the Cartesian plane, would it be possible to assign the pan to the x axis and the tilt to the y axis?
I am sorry if I am being unclear, I am doing my best.
Any help would be much appreciated!
