hi!
i am trying to make a detector that will count everytime an object passes through.
i am looking at the possibility of using photo interrupters as my sensor but all the sensors i could see have very small gaps. i am looking for a wider gap, as much as 15mm.
i am trying to look up fiber optic sensors, as i was told that it could be used in my application. i need some help on this though, i am not familiar with fiber optic sensors.
any suggestions on a sensor?
thank you

Just like you, I haven't heard about fiber optic proximity sensors. May I suggest an different approach? 15mm is not a very big gap. You can buy discrete LED and photodiode and mount them against each-other at any desired distance.
BTW, here's another good place for sensor-related topics: http://tech.groups.yahoo.com/group/sensorforum
