I’m working in a project that count the number of packages out of a production unit…
I have read a lot of articles that explain 2 kind of sensors :
1- IR Emitter - Receiver .
2- Laser Diode - Photocell.
I need the most accurate and executive solution that takes the following into consideration :
- The project will work almost 24/7.
- The project will be exposed to dust,noise,ambient light and vibration.
Thank you very much and sorry for my bad English >_<…
