Is it posible to detect the movement of a paper using a PIR sensor. Please be kind enough to help me.
Paper coming out of a laser printer is warm, so it may well set off a PIR (passive infrared). But you might be better off with a more optical system perhaps? A 'light detecter' based sensor would probably be more reliable given the high white contrast of the paper.
