OK, so yesterday I got distracted and left the fill pump running and I overflowed the table. So I’m playing with an electronic water level sensor. So here’s my 3D printed homebrew sensor, a little Rain Sensor circuit I had laying around for a while Guide for Rain Sensor FC-37 or YL-83 with Arduino | Random Nerd Tutorials and a 12V relay. This should mitigate that boo-boo! Looks promising. Will know for sure tomorrow.
Updates:
-
Oops! …did not realize it is 3-5V …I been hitting it with 12V all day and no magic smoke!
-
I think I can replace this circuit with a single NPN transistor and a couple resistors. Will try tomorrow.
