Identification number: KC-PI-2022/8

Type: Investment and Development Agency of Latvia (LIAA) mission “Sea 2030”

Project duration: 01.06.2022-30.06.2023

Project manager: Dr. Phys. Aleksejs Zolotarjovs, Institute of Solid State Physics, University of Latvia

Total budget: 222 222.22 EUR, from which 200 000.00 is ERDF budget (90%)

The aim of this project is to develop autonomous and energy-independent buoy for the purpose of monitoring water quality and indicators of aquatic microorganisms.

Project summary: 

Sea pollution in the Baltic region creates hazards to human health, marine organisms and can create devastating economic losses. This project offers technology for water quality monitoring offering rapid, online, and in-depth analysis of saltwater with the main market focus on sea farms. The technology is a portable, autonomous, fully automated spectroscopy laboratory buoy with networking capabilities and consists of three parts - a novel spectrometer device attached to a buoy; data acquisition/analysis software running on a microcontroller, and a cloud-based database with reference sample data. The main aim of the device in the scope of this project is a data-driven assessment of water quality directly affecting sea farm products, although the device can be used in other fields where continuous water quality measurements are needed (ecology-focused government organisations, harbours, oil platform operations, etc.). The novelty and market advantage of the technology lies in two main properties - a greatly reduced cost of the device when compared to the alternatives and the use of a novel spectrometer offering a much broader range of data thus expanding the list of measurable pollutants, be it through direct or indirect measurement. 

Tasks at ISSP UL:

ISSP UL is a project lead therefore is performing all project tasks – development of the prototype (including data analysis algorithms, servers and communication protocols), as well as performs commercialisation activities – communication with the industry and market analysis. 

 
 

Project progress information

Period 01.06.2022. - 31.08.2022 | 31.08.2022

In the first period of the project, the creation of the prototype is ongoing - several purchases have been made, the electronic circuit has been assembled, both the development of the existing software and the definition of communication protocols and data packets are being carried out. Successfull communication with the data server was established. In addition, much of the attention is devoted to the consumption and production of electricity using solar panels. Simultaneously with the development of the prototype, measurement tests and data adaptation for automatic analysis are carried out in the laboratory - water from various sources is measured with a spectrometer device that will be present in the buoy, and well-defined samples for calibration are developed. From the commercialization side of the project, communication is being carried out with the government water monitoring institutions, discussions have been started with various water pollution experts in several areas - ports, lakes, etc.
