How Hydrone Operates?
From river deployment to data storage — six stages of Hydrone operation.
System Initialization
ESP32 + Arduino Mega activates all components: sensor suite (pH, TDS, turbidity, temp), thruster ESCs, relay module, and 20m tether connection to the surface operator.
Deploy & Depth Control
ROV is lowered into the river. Active ballast system — water pump + compressor + solenoid valve — controls depth precisely. 2× vertical thrusters maintain position in the water column.
Navigate & Collect Debris
Operator steers Hydrone via tether. 4 thrusters (2 horizontal differential + 2 vertical 75°) navigate to polluted areas. Passive net opens automatically as ROV advances — capturing macroplastic without extra motors.
Microplastic Filtration
DC bilge pump draws water through 2 filter stages: Stage 1 pre-filter 20–50 µm (sediment/silt) and Stage 2 final filter 0.1 µm (microplastic). Particles collected in a removable transparent container.
Monitor & Transmit Data
Sensors record data every 2.5 seconds. ESP32 transmits to Firebase Realtime Database via tether. The web dashboard displays pH, TDS, turbidity, temperature, and depth live — with sparklines and status alerts.
Operation Complete
Operator closes the net via servo latch from the dashboard. ROV ascends using ballast + vertical thrusters. All operation data is saved to history and can be exported to Excel (CSV) for further analysis.
