$250-750 USD

Paid on delivery
I have a couple of liquid sensor using optical technology, which turns out to be unreliable. I need a redesign using capacitive technology that will be cheaper and more reliable. I want to the new design to offer same features (to the end users) and fit into current case, so I don't have retool everything. Besides design files (schematics, PCB Gerber and program), I also need prototypes being built. The specification is attached.
