Embedded Sensor Test Rig Development

I need a small sensor test rig built and delivered: • BME688 breakout (I already own a Pimoroni PIM575) connected to an ESP32 dev board • Firmware that logs raw gas resistance, temperature, and humidity at the sensor’s maximum sample rate to CSV over USB serial • A simple live plot on screen (Python script is fine) • Configurable heater profile (I’ll want fast-response settings, not the default IAQ profile) • Short written instructions so a non-engineer can run it I will run the physical test trials myself using a fixed protocol (provided after NDA). The work is the rig + software only. Deliverables: working firmware source, logging/plot script, wiring diagram or photo, run instructions. NDA and IP assignment required before the detailed brief is shared. Fixed price, two milestones: (1) rig demonstrated working on video, (2) source + documentation delivered.
