Not that i know much about sensors or electronics, but i believe this would be a bit harder to implement, the modules that come out of  home lights have a set of resistors and other small bit built into a small circuit.

that is a really good price, however!

hello there jaime,

  I have just recently bought 15 I.R. sensors for an installaition I  am
working on.
  I found two for around the $5-$6 range

i went with the first link because it is a rabbit, of course.

shouyld get them in a week or two.

i know a bit about hackingt them(not too hard to do it seems)

let me know how this project comes along as we might end up being a valuable
resource to one another.
