    Default Sensitive Reflective Light Sensor

    This might interest Tim.

    Ebay Reflective Light Sensor

    And an article here:

    Reflective Light Sensor Article

    They look interesting, but are rather expensive at 5 per sensor, so that's me out.

    The article was interesting. Unfortunately the use of floats falls foul of patents. I'm going down the path of capacitive sensors. I'm pretty sure it will be my solution.

    I just need to actually put some hours into it.

    Addendum, its not using floats my bad

    Apparently, the sensor is so sensitive, it can detect the difference when water is the medium, instead of air.

    I decided to do some more testing with my capacitive system and was disappointed, to much drift so I'm going to try out the OPB9000.

    Thanks for the heads up

    Hi Tim
    This is an interesting article where they have used the OPB9000 in a Medical Device.
