The Scuba BGA is a floating, solar-powered sensor buoy designed to provide early warning of harmful algal blooms, turbidity and other water contaminants.
The Scuba BGA (for Blue-Green Algae) is designed to monitor water quality, specifically algae, temperature, and turbidity. Real-time insights in these parameters will help to take action in time and prevent larger algae problems. Custom alerts will notify you when levels have gotten too high.
By continuously monitoring the water, the Scuba BGA eliminates the need for manual water sampling and spot checking. This device uses the fluorescence of the pigments in algae and cyanobacteria (blue-green algae) with this it detects the abundance of organism. Chlorophyll-a, present in all algae and cyanobacteria, is the most commonly used indicator of algal growth. Phycocyanin, typically present in freshwater cyanobacteria, is used as an indicator of blue-green algae. The Scuba BGA uses an excitation wavelength of 420 nm for chlorophyll-a and 575 nm for phycocyanin. The measured peak emission wavelengths are 670 nm and 642 nm, respectively.
Power and data transfer
Thanks to the integrated solar panel, the Scuba BGA is self-powered and can continue to operate for up to a year as long as the water does not freeze. Fully charged, it can function for 2-3 weeks without sunlight. The data collected by the Scuba BGA is sent to a web portal via 4G cellular tehnology. This system automatically switches between three carrier waves to optimise reception. It’s truly an all-in-one system complete with sensors, power supply, data monitoring trackers, and a powerful dashboard. The dashboard also tracks the GPS coordinates of your devices so you’ll always know where it is.
The buoy is suitable for both fresh and salt water and equipped with a built-in sensor wiper, to keep the sensor clean and functional.
Installation of the buoy is easy; simply place it in a waterway, connect it to an anchor (available separately) and it will automatically start collecting data.
The instrument measures the following parameters:

When the days get warmer in spring and summer, the risk of blue-green algae, or cyanobacteria, increases. The growth of blue-green algae is a sign that the water quality is declining: there are more nutrients such as nitrogen and phosphorus in the water on which these bacteria thrive. Many species of blue-green algae produce toxic substances that are harmful to humans and animals.
