I created and organized the research as living project files, with separate subsystem documents and a synthesis document, consistent with the project-doc workflow and targeted source-extraction approach :
-
I also created the sensor/integration/reliability stack:
-
Key breakthroughs:
- The sensing subsystem is the main project risk; the docs now clearly separate inline/wetted vs clamp-on PVC as the pivotal architecture choice.
- The current research-backed baseline direction is USB-C 5 V sink-only, a strong 3.3 V main rail, a WiFi MCU + RS485 architecture, and an optional higher-voltage ultrasonic rail only if bench evidence proves it is needed.
- The docs now explicitly capture that acoustic fixture quality, zero-flow offset calibration, temperature compensation, and cross-domain noise control are first-order design constraints, not cleanup items.
Ready.
