If that doesn't work, use two nails and a floating conductive ball to complete the circuit when the water raises.<span></span><br><br>On Monday, March 31, 2014, Justin <<a href="mailto:justin@slootsky.org">justin@slootsky.org</a>> wrote:<br>

I have a pump, but it doesn't have an auto shutoff, and it shouldn't run dry.<br>
<br>
I have a powertail that I can use to turn the pump on and off, so now all I need is a water sensor.<br>
<br>
Would this be as simple as two nails in a board with wires attached to the nails? Water is conductive, when the water completes the circuit, the Arduino notices and turns on the pump.<br>
<br>
Probably two water sensors, with the "on" sensor being above the "off" sensor to prevent it from triggering on and off too fast.<br>
<br>
Is anything wrong with my logic? Why won't this work? Do I need more than wires to make a water level sensor?<br>
