Hi All
Im looking for a device like a PIR but not infrared, I just want it to detect when something has moved passed it! the distance is no more than 2cm really
A PIr is is perfect but it detects heat movent I just want to detect movement
e.g
if move a pencil or any other object past it it will detect that some thing has moved past it
