As Arduino projects go, it isn’t very sophisticated. The circuit contains a sound detection module and an optoisolator. The code would easily fit on a piece of notebook paper.

You have to carefully look at [upir’s] Arduino thermal camera project because it intersperses pictures of what you expect an 8×8 sensor will produce with images produced by a much better camera.
