VARMAXAquaTech Platform
01 · VARMAX Vision

A modular aquaculture automation platform — not a single IoT device.

VARMAX combines a field gateway, secondary controller nodes, a LoRa farm network, optional 4G backhaul, aerator control, a farmer mobile app, a web platform, a backend and coordinated AI agents. The farm keeps running when the internet does not.

Prototype focus

Gateway + secondary node + LoRa + safe motor control

Design boundary

DO and current/voltage monitoring are not in current scope

Strategic principle

First reliable. Then intelligent. Then autonomous.

02 · Interactive 3D Farm

Field twin: ponds, aerators, nodes, gateway and uplink

Click any element to inspect it. Trigger the full command workflow, cut the internet link to see local autonomy, or fly the future feed drone. All telemetry shown is simulated for demonstration.

03 · System Architecture

Layered responsibility, controlled interfaces

Each layer has a clear responsibility and a controlled interface to the next. Cloud connectivity enhances the system; it never becomes a single point of failure for basic farm control.

The gateway keeps enough local state to continue safe operation during internet outages.
