I need a good material that I can stick on a gear that will reflect IR light. I've tried reflective tape and aluminum foil so far and while I got results they didn't reflect enough light back.
If you haven't guessed already I'm building a tachometer. I'm using a IR LED and a photo diode setup. So Im wondering If there is anything that I can pick up at a home depot that will help me out. Thanks.
P.S. Im using a PLC analog input and not a microcontroller, my code works fine its just I occasionally count "false positives" when there are changes in ambient light. This is just a learning exercise for work by the way.
