    Ultrasound Tank Level Meter

    We did a quick test in open air with the sensor firing inside a long piece of the pipe shown in the pictures (~2 inch). It then returned a constant distance, shorter than the length of the pipe, so we decided not to continue this path. In hindsight we could have tested it more thoroughly (e.g. with water inside the pipe) before dismissing it. Let me know if you decide to try!

    Glad to hear you got inspired!In this project, all the action is in the Arduino with display. This includes conversion from the mystical time unit that the ultrasound unit gives back to a distance in real units (and further to volume).In your case, if the tanks are close to each other, you could consider connecting six ultrasound sensors to the "well" Arduino, and have it select which sensor to use based on the trig value ( adding more cases to if (Serial.read() == xxx ) ). Then you can keep track of all fluid levels at once in the Arduino in the house and show the levels sequentially on the display (no need for switch).If the tanks are further away you could add a switch for the TX/RX pins and have separate Arduinos in each tank, but you would have to reset the Arduino in the...
