Hi! I need to detect PET bottles for my project. I'm looking for a sensor that I can connect to a microcontroller. I've seen some commercially available ones such as Omron's E3-ZB, however they are quite expensive.
I've noticed that PET sensors are photoelectric in nature, can anyone explain how they work? I would like to understand how they work and maybe I could create a simple circuit for it? Or are there other ways of sensing PET bottles? Thanks in advance!
