What Equipment Does Smart Shrimp Farming Need?
A shrimp pond system that truly covers the pre-dawn low needs four layers: sensing (sensors), control (controller + VFD), continuity (power and local logic) and visibility (platform and alarms). Missing any one layer is where systems fail when it matters.
Four-layer equipment checklist
| Layer | Equipment | What it does |
|---|---|---|
| Sensing | Fluorescence DO sensor (e.g. Y504-A, IP68 titanium, RS485 Modbus RTU), temperature / multi-parameter probe | Continuous DO and temperature — no membrane, low drift, optional auto-wiper against biofouling |
| Control | 4G aquaculture gateway/controller, waterproof VFD | Runs threshold logic locally and varies aerator speed on DO instead of crude on/off |
| Power | Intrinsically safe DC 48V architecture, storage and outage ride-through | Keeps the system alive through storms and outages, safer in wet environments |
| Platform | Cloud platform + mobile app | Live values, history curves, low-oxygen alarm push, centralized multi-pond management |
Where to place sensors
- At least one monitoring point per pond; on large ponds, place points by aerator group or zone — one point should not represent the whole pond;
- Install at the bottom water layer where shrimp actually live, while avoiding the strong turbulence directly under aerators and the feeding concentration zone;
- The point should represent typical pond conditions; final placement depends on pond shape, depth and aerator layout — confirm during a site survey.

Can an existing pond be retrofitted?
Yes — that is the most common path. Retrofits usually run in three steps:
- Start measuring: add the DO sensor and controller, run a 24-hour curve and learn your pond's own low-oxygen pattern;
- Then close the loop: once the pattern is known, add the VFD and move aerators from manual/timer control to DO-driven control;
- Finally secure power: for ponds exposed to storms or outages, add DC 48V supply and ride-through as the safety net.
You do not have to do it all at once. Starting to measure is the single most valuable step — without continuous data, every threshold and automation rule is guesswork.
Three things buyers overlook
- Sensor maintenance: prefer fluorescence (no membrane) with auto-cleaning, otherwise fouling means constant recalibration;
- Offline behaviour: control logic must run locally so aeration still follows thresholds during a network outage;
- Power safety: ponds are wet; intrinsically safe low-voltage supply addresses both leakage risk and outage ride-through.
Frequently asked questions
- What equipment does smart shrimp farming need?
- At least four layers: sensing (fluorescence DO sensor, temperature/multi-parameter probe), control (4G controller and waterproof VFD that varies aerator speed on DO), power (intrinsically safe DC 48V supply with outage ride-through) and platform (cloud platform and mobile app for live data, alarms and multi-pond management).
- How many DO sensors does a shrimp pond need?
- At least one monitoring point per pond; on large ponds place points by aerator group or zone so a single point does not represent the whole pond. The exact count depends on pond shape, area, depth and aerator layout — confirm with a site survey.
- Does aeration still work during a network or power outage?
- By design, yes: the 4G controller runs threshold logic locally, so aerators keep following DO during a network outage. On the power side, the intrinsically safe DC 48V architecture with ride-through keeps the system running through storms and outages.
- Can an existing shrimp pond be retrofitted?
- Yes, and it is the most common route. Work in three steps: add sensors and a controller to capture a 24-hour DO curve, then add a VFD for closed-loop aeration, then secure power with DC 48V and ride-through. Starting to measure is the most valuable first step.
