I am using OMRON EE-SM3 Opto-Switch (Sensor TX + RX Unit) for inputting clock pulses to uController through its timer pin. The problem is that when I pass an opaque object through its slit once, it counts it multiple times (i.e. counter increments more than once).
Is there any remedy circuit for such a problem, so in result I could get one pulse per pass. I don't intend to use any Shmitt-Trigger device. What is the most economical solution. The circuit I am using currently is the one given in the test circuit section of the sensor's datasheet given above in the link.
