& Grey Water Sensor - 2022

Grey Water Sensor - 2022

Need to redesign the new unit to ensure that the switches and wires are sealed away from the grey water. I sure didn't know gray water was that corrosive!
   
First step was to clean it all up.
   
3D printed a shallow cap to seal the bottom. All put together.
   
New laser engraved label. I added 2 LEDs to show the state of the float switches.
   
Big Whoops ! I mounted the Full Switch upside down ! Found this out when I installed it. See the photo above "All put together"
   
This is the correct way ! The 2 black things are float switches. All sealed and use a magnet to activate. The left (empty sense) switch is closed when the tank is empty shutting off the pump. The right (full switch) is closed when the tank is full turning on the pump. Up and running!
