Water-Quality Monitoring, Equipment Control and Anomaly Alerts
Monitor water quality and equipment status centrally, and connect aerators, pumps and other devices for remote operation, schedules and anomaly alerts. Monitoring parameters, electrical interfaces, network conditions and offline behavior are confirmed by project.

Common Aquaculture Monitoring Risks
Manual sampling and distributed equipment can leave gaps in water-quality records and alarm coverage.
Manual equipment restart
Restarting aerators across several ponds requires staff to travel between control points.
Limited coverage outside staffed hours
Rain, heat and oxygen changes may occur when fewer staff are present on site.
Limited production history
Without historical curves, operators cannot compare water conditions and equipment operation across production cycles.

AquaLink system architecture
The architecture separates pond-side sensing, cellular backhaul, local control and on-site alarms.
- Sense and transmitWater-quality and weather sensors connect through Y201-L pond-side transmission to a Y201-G 4G gateway.
- Control and escalateY403-11-L handles local I/O linkage while Y901-L provides a dedicated on-site alarm path.
Pond Data with On-Site Weather Context
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.

Mesh network, 1DI/1DO, LoRa. Local Mesh linkage controller for aerator or valve control points.
Y901-L
Multi-Point Wireless Alarm
LoRa communication and multi-point wireless mesh linkage for pond-side and duty-room escalation.
Monitoring, Local Control and On-Site Alarms
The deployment can combine water-quality monitoring, local equipment linkage and on-site alarms.
Monitor water quality
Collect dissolved oxygen, pH, water temperature, and optional sensor data through pond-side serial gateways.
Link local equipment
Use Y403-11-L local wireless I/O modules for aerator or valve linkage rules without relying only on cloud commands.
Escalate on site
Use Y901-L alarms to notify pond-side and duty-room staff when a pond needs immediate attention.
Aquaculture Applications
The same architecture can be adapted to freshwater ponds, seawater sites, shrimp and crab farms, and hatcheries after a site review.
Freshwater fish ponds
Monitor DO, pH, and temperature; link low-oxygen thresholds to aeration and on-site alarm workflows.
Seawater aquaculture
Add rainfall and forecast context so operators can prepare inlet valve and aeration actions before water conditions shift.
Shrimp and crab farming
Track oxygen and temperature risk at night and use alerts to guide feeding and emergency response.
Hatchery and nursery
Use tighter monitoring and alarm workflows for temperature and oxygen-sensitive young stock.
Outdoor Deployment Considerations
Lightning, power failure, and electrical safety are treated as part of the aquaculture system design.
Lightning protection
Lightning protection and grounding practices are part of the aquaculture system design for humid outdoor pond environments.
Isolated control
Low-voltage sensor sides and isolated control outputs help separate sensing from high-power aerator circuits.
Power-event awareness
Cloud and on-site alarm paths help operators know quickly when power events threaten aeration availability.

Deployment
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 deployment combined real-time monitoring, remote control, weather data and local alarm escalation.
Frequently Asked Questions
Answers for farm owners and aquaculture technicians evaluating monitoring, local control, reliability and project scope.
How long do the sensors last when submerged in water?
Service life depends on the sensor type, water conditions and maintenance schedule. Confirm the selected sensor model and replacement interval before deployment.
Can LoRa cover a large fish farm?
LoRa coverage can be evaluated for pond-side points, while relay or local I/O may be used where the layout requires it. Water, terrain, vegetation, metal structures, antenna height and node power affect the usable link, so a field test may be required.
What happens during a storm or power interruption?
Outdoor protection, local control and alert behavior depend on the selected equipment and project configuration. Confirm enclosure, grounding, backup power, local rules and recovery behavior before deployment; the cloud alone should not be the only control path.
How is electrical safety handled?
Sensor circuits and aerator circuits must be designed with appropriate isolation, overcurrent and leakage protection. The platform and I/O modules do not replace the site electrical design or required protective devices.
What if 4G signal is poor?
Cloud access needs a suitable uplink. Where 4G is weak, local LoRa or wired backhaul can be evaluated for field monitoring and control, but the actual topology and offline behavior must be confirmed for the site.
