Autonomous tinyml universal multi-gas & airborne hazard sensor calibration framework via triangulated gravimetric, colorimetric, and reference metrology

Title: Autonomous TinyML Universal Multi-Gas Sensor Calibration Framework via Triangulated Metrology Target Platform: Halo.science Partnership Listing Technology Readiness Level: TRL 4 – Validated in Lab Conditions Target Analytes: VOCs, Inorganic Gases (CO, NO2, H2S, NH3), and Toxic Industrial Chemicals

1. Executive Summary Low-cost electronic gas sensors suffer from baseline drift, non-linear decay, cross-sensitivity, and lack of field calibration. Project Halo-TTPV pairs a patented Bare Metal Fusion Engine with a three-node Traceability, Calibration, and Performance Verification (TTPV) framework. By integrating micro-gravimetric mass-loss metrology, colorimetric chemical verification, and certified reference instrumentation, Project Halo-TTPV trains an embedded TinyML Brain on microcontrollers for autonomous baseline auto-correction and real-time health-risk evaluation at the edge.

2. Technology Readiness Level (TRL 4 - Validated in Lab) The core physical metrology, chamber dynamics, and mathematical algorithms are validated in a lab environment: a) Hermetic Multi-Gas Chamber: Verified a 13.3L sealed chamber with micro-vortex fan convection for rapid flash evaporation and gas mixing.

b) Gravimetric Micro-Metrology: Primary mass-loss tracking using a Sartorius 0.001 mg microbalance via capillary touch-off (W1 - W2), bypassing syringe markings.

c) Mathematical Traceability: Proven ideal gas law modeling mapping microgram mass loss directly to theoretical PPM ground truth.

d) Triangulation: Captured UART telemetry from multi-gas sensors and verified against Gas Tec colorimetric stain tubes.

3. Eligible Partnership Models We are open to flexible collaboration frameworks on Halo.science: a) Co-Development: Jointly engineer micro-vortex chambers, C++ libraries, and TinyML neural networks.

b) Licensing: Acquire commercial rights to embed patented Bare Metal Fusion Engine algorithms and TinyML firmware into proprietary hardware.

c) Pilot or Trial Engagement: Deploy the TTPV chamber architecture and calibration framework in industrial facilities for field benchmarking.

d) Sponsored Research: Fund target expansions to additional toxic gases, expanding the gravimetric matrix and neural models.

e) Equity Investment: Capital investment to accelerate IP protection, hardware production, and global commercial scaling.

4. Technical Architecture & Triangulated Metrology a) Node 1: Absolute Gravimetric Primary Standard. Uses a Sartorius 0.001 mg microbalance for reverse-weighing (W1 - W2) of capped micro-dispensors to calculate exact chamber PPM.

b) Node 2: Colorimetric Chemical Benchmark. Draws chamber air through Gas Tec chemical stain tubes to visually verify phase transition.

c) Node 3: Analytical Reference Standard. Integrates laboratory reference analyzers (PID, NDIR) to capture concentration dynamics.

5. Embedded TinyML Brain & Fusion Engine a) Register Execution: Runs directly on microcontrollers without OS overhead for microsecond execution.

b) Dynamic Compensation: Ingests raw sensor streams, temperature, and humidity to auto-correct zero-point drift.

c) Health Risk Engine: Translates calibrated PPM into immediate safety metrics (STEL, TWA) for autonomous safety control.

6. Commercialization & Partner Resources We seek partners to advance Project Halo-TTPV from TRL 4 to commercial deployment via funding for IP filings, access to reference hardware, and industrial field pilot testing.
