Freshwater fish ponds
Monitor DO, pH, and temperature; link low-oxygen thresholds to aeration and on-site alarm workflows.
Y201-L + Y403-11-L + Y901-LAquaLink makes pond water quality visible 24/7, links sensors to aerators and alarms, and brings dissolved oxygen, pH, temperature, on-site weather, and cloud alerts into one operating view. Free cloud platform. No license fees.

The most expensive pond problem is the hidden one that happens at night, in rain, or across scattered aerators.
A morning water sample cannot reveal a dissolved oxygen crash that happened before sunrise.
Manual restart across many ponds turns a storm or outage into a farm-wide race.
Rain, heat, and oxygen dips often combine during the hours with the least staff coverage.
Without historical curves, operators cannot reliably copy the best conditions from one cycle to the next.

Planned flow: YenGear IoT Cloud with weather data -> Y201-G 4G gateway -> Y201-L LoRa pond-side data transmission -> water quality sensors and small weather station -> Y403-11-L local linkage control -> Y901-L wireless alarm.
Air temperature, humidity, rainfall, and external weather alerts give operators context before a storm reaches the ponds.
Small weather station readings are viewed alongside dissolved oxygen, pH, and water temperature so pond changes are not interpreted in isolation.
When rainfall and forecast warnings are combined with pond trends, farms can prepare aeration, drainage, valve actions, and inspections earlier.

YenGear IoT Cloud supports daily monitoring, alerts, remote control, historical data, and optional customization.
Core cloud access is provided with the hardware, without license or annual platform fees stated in the page plan.
Check pond status, alarms, and control points through app and web access for remote operations.
Review on-site weather station data with weather forecast context and pond trends.
Archive curves by pond and cycle to turn experience into repeatable operating data.
Monitoring, local control, and on-site alarms cover the moments when ponds need fast response.
Collect dissolved oxygen, pH, water temperature, and optional sensor data through pond-side serial gateways.
Use Y403-11-L local wireless I/O modules for aerator or valve linkage rules without relying only on cloud commands.
Use Y901-L alarms to notify pond-side and duty-room staff when a pond needs immediate attention.
The plan preserves multiple farm categories and product combinations, so this section remains fallback raw.

Monitor DO, pH, and temperature; link low-oxygen thresholds to aeration and on-site alarm workflows.
Y201-L + Y403-11-L + Y901-L
Add rainfall and forecast context so operators can prepare inlet valve and aeration actions before water conditions shift.
Y201-G + Y403-11-L + Y901-L + weather station
Track oxygen and temperature risk at night and use alerts to guide feeding and emergency response.
Y201-L + Y201-G + Y403-11-L + Y901-L
Use tighter monitoring and alarm workflows for temperature and oxygen-sensitive young stock.
Y201-L + Y403-11-L + Y901-LLightning, power failure, and electrical safety are treated as part of the aquaculture system design.
A direct raw case-study block based on the planning document.
Water quality sensors in each pond send data through Y201-L LoRa nodes to a Y201-G 4G gateway. Y403-11-L modules handle local aerator linkage and Y901-L alarms notify pond-side and duty-room staff.
The on-site image gallery below uses the six case photos from the planning folder.
Water quality issue response moved from reactive checking to real-time monitoring, remote control, weather-aware preparation, and local alarm escalation.






Answers for farm owners and aquaculture technicians evaluating deployment, reliability, safety, and cloud platform cost.
The planning document describes dissolved oxygen sensor service life as about 1-2 years with membrane cap maintenance, pH electrode life as about 1-1.5 years, and the sensor body as designed for more than 5 years with maintenance.
For open pond environments, the solution uses LoRa for long-range pond-side transmission and Y403-11-L Mesh linkage where relay and local control are needed.
The system design includes outdoor protection, local linkage that does not depend only on cloud commands, and weather-aware alerts before severe conditions arrive.
The plan separates low-voltage sensor circuits from high-power aerator circuits and uses isolated control outputs plus site-side leakage protection design.
The page plan states that core YenGear IoT Cloud functions are free with the hardware, while white-label customization, private deployment, or advanced API integration can be charged separately.
The 4G gateway path supports cellular cloud access, while local Y403-11-L linkage and Y901-L alarms can still provide on-site control and alert functions without depending on the cloud path.
Start with a pond assessment and design sensing, linkage, weather, and alarm layers around the way your farm actually operates.
