Data-Driven Aquaculture Era
High-density farming demands continuous monitoring of DO, ammonia, pH, and turbidity. Traditional manual sampling (1-2x/day) misses critical fluctuations. GWQ-MP200 delivers multi-parameter, closed-loop automation for modern shrimp/fish farms.
Core Value Proposition
-
1–6 channels: DO/pH/Ammonia/Turbidity/Conductivity
-
2x RS485 + Modbus-RTU → Cloud & mobile alerts
-
6 relays for auto-start aerators / pumps
-
8GB TF card local backup, offline storage
4 Major Pain Points in Aquaculture
Traditional methods fail to ensure stability in intensive farming
Incomplete Parameters
Most farms only measure DO, ignoring ammonia & nitrite — silent killers.
Poor Data Continuity
Manual sampling fails to capture nighttime DO dips & post-feeding ammonia peaks.
Low Automation
Aerators & valves rely on manual operation; high risk of nighttime hypoxia.
Compatibility Issues
Proprietary protocols create data silos, no unified remote management.

System Integration
GWQ-MP200 controller (wall mount) + digital sensors
RS485 daisy-chain | 6 relays → aerators / inlet valves
2x 4-20mA + dual RS485 to SCADA / cloud
-
Communication: 2x RS485 (Modbus-RTU), analog out
-
Storage: 8GB TF card, 90+ days trend logging
-
Auto temperature compensation
Plug & play digital sensors — custom cable length, immersion/thread mounting. RTOS ensures high reliability, touch screen for easy on-site operation.
Closed-loop automation — DO below threshold → relay triggers aerator; pH abnormal → inlet valve control. Reduce night shifts & labor costs.

Real Case: Yancheng, Jiangsu · Largemouth Bass Farm
From $20k annual losses to near-zero hypoxia events
Background
12 standardized ponds, high-density intensive farming (150 tons/year). Before upgrade: only portable DO meter, two ponds suffered massive fish kill in summer 2024 due to nighttime oxygen crash — direct loss > $28,000 USD. Frequent manual inspections but ammonia spikes remained undetected.
Implementation
One GWQ-MP200 with 5 digital sensors (DO, pH, Ammonia, Turbidity, Conductivity). 6 relays controlling 12 aerators (via intermediate relays). Data uploaded to cloud platform via second RS485, farm manager receives real-time alerts on phone.
Results after 6 months
95%
Faster ammonia detection
70%
Labor hours saved on aeration checks
87%
Reduction in fish mortality loss
“GWQ-MP200 is our electronic night watchman. When DO drops, aerators start automatically — zero hypoxia deaths during the last hot season!”
— Mr. Wang, Farm Director
Key Improvements
✅ DO monitoring: from 2x/day → 24/7 real-time
✅ Alert response: 2-4 hours → under 5 minutes
✅ Ammonia anomalies instantly flagged
Payback period
Reduced mortality alone recovered equipment cost within one season. Energy savings + labor reduction further boost ROI.
Why GWQ-MP200 for Aquaculture?
Multi-parameter flexibility — up to 6 parameters in one unit, reduce hardware cost.
Smart relay control — 6 relays (250VAC/3A) drive aerators, feeders, pumps.
Remote visibility — dual RS485 to PLC/cloud, mobile alarms via Modbus-RTU.
Data logging — 8GB TF card, historical trends for better feeding & harvest planning.
