these sensors don't detect PET specifically. They are capable of detecting transparent objects, of which PET roughly falls into.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!
The BIG question, is what is your background noise, or resolution. Will a homogoneous stream of materials be passing, or will one of several known items be passing? If your object is to identify if the object being placed in front of some sensor is either metalic, paper, or PET, no problem. If all are mixed together, your solution will likely include pre grading of materials, to the point that your background noise is reduced to tolerable levels.
