Altium RS485 Vibration Sensor PCB
Budget: $750 – $1,500 USD
I have already outlined the electrical requirements and shared a preliminary parts list:
• Full specification: https://www.esocore.com/docs/sensors/vibration-sensor
• Preliminary BOM: https://www.esocore.com/docs/bom/vibration-sensor
Now I need the design turned into a production-ready solution. The board can follow a standard-size footprint; size is less important than reliability and noise-resilience.
Your scope covers both hardware and embedded work:
1. Capture the schematic and complete the PCB layout in Altium Designer, observing good mixed-signal practices for a low-noise vibration sensor front-end and a robust RS485 interface.
2. Refine the Bill of Materials so it is ready for procurement—every line must include manufacturer, exact part number, package, and key specs.
3. Write firmware that handles sensor sampling, basic filtering, and Modbus-style communication over RS485. Keep the code clean and well-documented so future feature additions (e.g., optional I2C, SPI, or UART extensions) are straightforward.
4. Build, assemble, and bring-up at least one prototype; verify performance against the linked spec and share test logs/oscilloscope captures.
5. Deliver manufacturing outputs: Altium project, Gerbers, pick-and-place, finalized BOM, compiled HEX, source code, and a short validation report.
Acceptance will be based on the prototype meeting the sensitivity, bandwidth, and RS485 communication criteria stated in the spec, plus error-free compilation of all files on my end.
If you have quick access to low-volume assembly or can suggest component alternatives to improve lead times, let me know in your proposal.
