Measurements per day from single sensor


Simultaneously measurable parameters


Datasets in database already analysed

Fully automated optical spectroscopy laboratory placed underwater to get unprecedented selectivity and sensitivity of measurements!

Our main focus:

  • Selectivity – massive struggle for conventional sensors – solved by novel devices and analytical methods
  • Precision in relative and absolute measurements
  • Autonomous, maintenance free operation – ready for Industry 3.0
  • Low cost of deployment and operation – true IoT device, web-interface data presentation, alerts and easy integration in existing systems

Confirmed measurable substances:

  • Chlorophyll, Phycocyanin fluorescence and absorption
  • Distinction between different Chlorophyll types and pheophytins
  • Dissolved organic matter (DOM), humic substances
  • Overall absorption of water using incident light
  • Detection of algae growth on the surface of water
  • Non-fluorescent components (sand, soil, particulates, trash)
  • Presence of oils on the surface of water
  • CMOS sensor for visual water inspection

• Carefully chosen optical system combines filters, LEDs and detectors

• From CAD to PCBs, optical systems, electronics and waterproof cases – all tailored get most robust and versatile operation

• Full spectrum measurements with outstanding dynamic range and sensitivity, all made with different excitation wavelengths


• Full automation – designed with remote operation and data collection in mind

• Auto-calibration, data acquisition, data management and storage

• “plug-and-play” – no need for data loggers, servers and vsualization


• Sensor is tested in a controlled laboratory environment – with predetermined concentrations of components (Chlorophyll, Phycocyanin, Carotenoids etc.) inside water with varying dissolved organic matter (DOM) amounts

• Data from all sensors is collected with blocks of metadata for ease of deployment in the future

Applications for the device:


Better water – better fish. The device is used to determine the quality of water near fish farms – monitoring the amount of bacteria, food and contaminants. The measurements can be used to move the farm, increase/decrease food amounts for better performance and lower the risk of stock loss due to sudden changes in water quality.


Desalination and water filtration often requires expensive and easily damaged filters – the sensor can be inserted at the intake of filtration plants to quickly assess the quality of water before it touches the filters – preventing premature failure thus saving resources on maintenance and replacement of filters.

Water pollution monitoring

Phytoplankton blooms can be dangerous and harmful for aquatic organisms. Moreover, with ever increasing effects of anthropogenic activity, the monitoring of sea and ocean water is of increased priority. The sensor can be used in points of interest, and separation of different chlorophyll components is crucial for the task!
