S.E.N.S.E — Sensor Enabled System for Safety & Emissions

Architecture

Controller: ESP32

Intentional safety separation

Local safety logic

The ESP32 independently handles gas detection, hard gas limit, adaptive anomaly detection, emergency confirmation, valve closure, and buzzer activation.

Cloud intelligence

The web platform handles monitoring, historical storage, analytics, AI interpretation, and reporting. It has no hardware-control routes.

Offline behavior

If Wi-Fi or cloud service is unavailable, local ESP32 detection, valve closure, buzzer activation, and emergency response continue independently.
