Incident detection and localization prototype

Incident detection and localization prototype using ESP32 microcontrollers.

ESP32MicroPythonFlaskMesh RoutingManim

Problem

The idea: if one node detects a signal and cannot reach the backend, it forwards to a nearby node that can. A Flask service ingests the packets and persists them. Trilateration logic pinpoints the coordinate origin of a sound across synchronized devices on a local WiFi network.

Implementation

Evidence

Working end-to-end prototype demonstrated at a hackathon. Two nodes, trilateration concept validated.

Media

Graph transformation explaining routing behavior.
Simulation pass: packet movement between nodes.
Final prototype walkthrough sequence.

Constraints & next step

Built for a hackathon. Two-node prototype under time pressure. The ESP32 firmware tries to send telemetry directly first. If that fails, it forwards to a peer over RF. The peer relays to the backend.

Manim scenes explain the graph behavior visually, because slides are boring. The next step is stricter payload validation, auth at ingest, and moving from CSV logs to a real database.
