Motion Tracking. It's very common in computer science, yet all too often relies on camera sensors. I'm currently working on a project that would possess basic motion tracking ability without using camera sensors. To do so, I intend on using an array of Passive Infrared (PIR) sensors. However, the common PIR sensor (RadioShack.com Official Site - America's Technology Store) PIR sensor costs $10 each and only gives single-bit output and has a fresnel lens that spreads its field of view in every direction. What I would like is an array of raw PIR (like here: PIR Sensors and PIR Modules) that would be more compact and give more information. If used correctly, it should theoretically be able to draw information about the direction of the motion and possibly even speed instead of just HIGH or LOW.
The only thing is, as far as I am aware, no one else has tried to interface these with an Arduino. I'm currently wondering how feasible it would be to do this. I am relatively new to electrical engineering and taught myself everything I know (except for the Arduino book and Arduino reference page), so I have a basic understanding with gaps here and there.
For the tl;dr people: I want to interface these PIR Sensors and PIR Modules PIR sensors, not these RadioShack.com Official Site - America's Technology Store sensors, with the Arduino and I don't know if it's possible.
Thank you,
