Multisensor Embedded System Design
Budget: $250 – $750 USD
I’m building a compact embedded platform that can simultaneously collect data from temperature, pressure, and motion sensors—plus any other common sensors you feel are appropriate—process that information locally for real-time control, and then push the results out through a robust communication interface.
The core of the job is end-to-end: firmware that handles reliable sensor acquisition over I²C/SPI/UART, a control loop that can react in microseconds, and a wired or wireless link (BLE, Wi-Fi, or CAN are all acceptable) to stream logs or accept remote commands. Whether you favour an ARM Cortex-M, ESP32, or another microcontroller is up to you as long as you justify the choice in your response and keep power efficiency in mind.
To keep everything transparent, I’ll need the following at hand-off:
• Source code (C/C++ or Rust) with inline documentation
• Schematics and PCB files (Altium or KiCad)
• A brief test report showing each sensor channel, the control output, and the comms link working together
Please attach a detailed project proposal outlining architecture, key components, estimated timeline, and any past designs that prove you’ve tackled comparable sensor-heavy systems before. Concise but complete proposals will stand out.
