Portable Arduino-based Water Tank Gauge

Those of you with rainwater tanks at home or in rural situations would understand the difficulty of accurately determining how much water is left. You could have a trained ear and be able to knock the side of the tank for a rough estimate, however doing so is not for everyone. A member of our Freetronics forum has instead devised and published details of a portable ultrasonic water tank gauge that can quickly show the amount of water left in a tank using a simple 'fuel gauge' style readout:

Full details including the Arduino sketch are available to download. Although the author used a Freetronics Eleven board:

perhaps consider using a Leostick to reduce the total size and increase portability of the gauge.
