State-Aware Decisions
The controller tracks transition history, not only current readings, which reduces unsafe ON/OFF relay switching.

HydroSmart DNA: What Makes This Unique
Dual Control Integrity
Manual override is available for operators, while autonomous safety constraints remain active in parallel.
Real Hardware Proof
Validated on ESP32 + relay + sensors as a complete sensing-to-actuation loop, not a simulation-only build.

How it works
System Architecture
-
Hardware Sensing
ESP32 continuously reads water flow rate, temperature, current, and voltage from physical sensors.
-
Data Transmission
Data is securely transmitted to the Python backend through an API/websocket pipeline in real-time.
-
Intelligent Processing
The Model-Based Reflex Agent evaluates current thresholds and historical state transitions to determine the next optimal state.
-
Actuation
Backend sends precise control commands to the relay channel (ON/OFF/AUTO/SAFETY) to manage the motor.
-
Operator Visibility
The web dashboard receives live telemetry and action logs, providing operators with full situational awareness.
