Solar-powered ultrasonic algae control with remote monitoring
Sentinel AIQ™ is a floating, solar-powered algae remediation platform combining Pulsar 4400 ultrasound, rugged flotation, onboard telemetry and optional water-quality monitoring.
Designed for large waterbodies and remote sites, Sentinel helps defend water against algae and biofilm without chemical dosing, while giving operators better visibility over system performance and water health.

A complete floating platform for algae control and water visibility
Sentinel AIQ is designed as a standalone floating system, providing solar power, flotation, ultrasonic algae remediation and remote operating visibility in one field-ready package.
The standard Sentinel AIQ package includes the Base Camp™ flotation system, a Pulsar 4400 ultrasonic remediation appliance, solar power, onboard IoT and telemetry. Sentinel AIQ+ adds a water-quality monitoring system with connected field sensors.
Key Sentinel features
- Pulsar 4400 ultrasound for algae and biofilm control.
- Solar-powered operation for remote or hard-to-cable sites.
- Onboard telemetry and IoT for operating status and remote visibility.
- Optional AIQ+ sensors for live water-quality monitoring.
- Rugged floating platform designed for practical field deployment.
Broad-spectrum algae control with solar and telemetry built in
A floating, always-on defence system for waterbodies
Sentinel deployed
The floating platform is positioned for coverage, power access and site-specific waterbody conditions.
Ultrasound operates
Pulsar 4400 transmits ultrasonic frequencies to target algae and biofilm through the water column.
Telemetry reports
Onboard systems capture and transmit operating status, with AIQ+ adding live water-quality sensor data.
Water is managed
Operators can monitor system performance, review water-health trends and support long-term algae control.
Ultrasonic algae control plus real-time operating visibility
Sentinel combines the Pulsar 4400 ultrasonic remediation appliance with a rugged floating platform and solar power. The system can operate with minimal manual intervention compared with repeated chemical treatments.
Onboard telemetry and IoT systems capture and transmit operating status to remote monitoring crews. With AIQ+ enabled, sensor data is transferred to the cloud where operators can view water-health dashboards and analyse trends from any web-connected device.
AIQ+ water-quality sensor options
- Blue-green algae
- Chlorophyll A
- Conductivity
- Dissolved Oxygen
- ORP
- pH
- Temperature
- Turbidity
Designed for reservoirs, lagoons, lakes and remote sites
Sentinel is designed for large or difficult-to-access waterbodies where shore power is unavailable, cable runs are impractical or operators need a more self-sufficient algae-control platform.
The system supports water utilities, wastewater treatment sites, councils, municipalities, agricultural storages, lakes, ponds and large managed water assets where reliable operation and remote visibility matter.

Where Sentinel AIQ fits
Drinking water utilities
Helps protect reservoirs and raw-water assets from harmful algae pressure, filter blockages and operational disruption.
Wastewater treatment plants
Supports algae control in lagoons and basins where ageing infrastructure, labour shortages and strict regulation create pressure.
Councils, lakes and ponds
Provides chemical-free algae control and optional live water-health monitoring for public lakes, ponds and managed waterbodies.
Sentinel AIQ and Sentinel AIQ+
Choose the package based on whether your site needs ultrasonic algae control alone, or ultrasonic algae control with live water-quality monitoring and cloud-based data access.
| Package | Included | Best suited for |
|---|---|---|
| Sentinel AIQ | Base Camp™ flotation system, Pulsar 4400 ultrasonic remediation appliance, solar panel, onboard telemetry and IoT. | Sites needing floating solar-powered algae control with remote operating visibility. |
| Sentinel AIQ+ | Sentinel AIQ package plus water-quality monitoring sensors and cloud data access for live readings and dashboards. | Sites needing both algae control and water-health data for monitoring, reporting or operational decisions. |
Designed for broad treatment areas
The Pulsar 4400 platform is designed for large reservoirs, lakes and managed waterbodies, with broad ultrasonic coverage and high precision targeting across green algae, blue-green algae and biofilm.
Actual performance depends on waterbody shape, depth, obstructions, mixing, inflows, algae type and installation position. Algae Control Australia can prepare a site-specific layout and coverage recommendation.
Indicative coverage from current product information
- Green algae: up to 150 m radial coverage.
- Blue-green algae: up to 400 m radial coverage.
- Biofilm: ultrasonic biofilm support as part of the Pulsar 4400 platform.
- Power: solar-supported floating package for remote deployment.
What we need to assess your site
- Waterbody dimensions and approximate surface area
- Average and maximum depth
- Photos, drone images or site maps
- Known algae type or water test results, if available
- Power availability, cable limitations or need for solar
- Monitoring requirements, reporting needs or dashboard expectations
- Current issues such as scums, odour, biofilm, poor clarity or filter blockages
Site-specific design for Australian waterbodies
Sentinel performance is strongest when the correct package, placement, sensor configuration and telemetry setup are matched to the site.
For high-nutrient waterbodies, Sentinel may also be combined with PBE biological support, nutrient binding or circulation depending on the cause of the bloom pressure.

Frequently asked questions
Is Sentinel a chemical treatment?
No. Sentinel uses ultrasonic algae control through the Pulsar 4400 platform rather than chemical dosing.
What is the difference between AIQ and AIQ+?
Sentinel AIQ includes the floating platform, Pulsar 4400, solar and telemetry. AIQ+ adds water-quality sensors and cloud data access.
Can Sentinel run off-grid?
Yes. Sentinel is designed with solar power to support remote or difficult-to-cable installations.
What can AIQ+ monitor?
AIQ+ can monitor parameters such as blue-green algae, chlorophyll A, conductivity, dissolved oxygen, ORP, pH, temperature and turbidity.
Can data be exported?
Yes. The system can support data export into other applications, including plant supervisory systems and data or statistical analysis platforms.
Where is Sentinel best used?
Sentinel is well suited to reservoirs, lakes, ponds, wastewater systems and remote waterbodies where solar power and remote monitoring are valuable.
