    Non-Contact Liquid Level Sensor Adapter

    I currently am making a BOB adapter that allows you to connect optical sensors similar to the ones used in the DDR to your APEX IO port, but my next project or version I am tinkering with adding support for these type of sensors. They are non contact and sense the water level through pipes, or tank sides. You could use them as a cheap on/off flow meter on pipes (does it have water or not), use them for ATO sensors on your sump, or even put one on the outside of your skimmer cup to alert you when its full. The sensors are like $5-9 each on ebay. I will start working on a prototype now if people are interested.

    Anything that keeps stuff out of the nasty salt water and away from the snails is a good thing.

    Wow! This is interesting. I'm still not sure I understand how they sense water through pipes? What kind of sensor does it utilize?

    It's ultrasonic. Sends ultrasonic waves into the pipe and measures them on reflection. There's a significant difference between an empty pipe and a pipe with the presence of water. Won't measure the actual flow like the FMM, but can produce a binary signal conducive to an input on the breakout box.

    Haven't had time to dig in. Maybe tonight I'll do some prototyping.

    Any capacititive proximity sensor with the appropriate sensing range will work as well. I've been using the same sensor for the last 10 years. I have to power it separately and then run it to the coil side of a dry contact that's connected to my BoB

    I know this is an old thread, but I would like a non-contact sensor for my 55 gallon water change container.

    Do you have a schematic of how you wired this up?

    Thanks,
    David
