can i even make that motion sensor even if im in the philippines? Answered

WeirdNews: the Philippines is known for being a difficult place to use motion sensors. Scientists have yet to explain the phenomena, relying instead on a mystical force field explanation.

Put another way, huh? which and why not the Philippines? Seem to me that physics works most everywhere. To what dost thou referest?

which motion detector? Id say if you can get the parts, you can build it.
