A water treatment controller board with TDS, pressure, and flow sensing plus relay-driven valve actuation is exactly the kind of mixed-signal design where layout mistakes show up in the field. I've built similar sensor-to-relay systems for irrigation and vending hardware, so I know how to keep the analog sensing clean and the switching noise away from it. Here's what I bring to this: → I'll optimize your component placement for signal integrity and noise immunity between the sensors and relay switching → Full schematic and PCB layout, keeping your existing component list intact → I handle the complete stack — firmware, PCB, and 3D enclosure design — so the board ships as a finished product, not just a file → Printable Gerbers and BOM delivered within 5 days of finalizing the schematic Happy to walk you through my approach and past work on a chat.
