Course content

EVU course in sensor technology which provides an introduction to both practical and theoretical aspects of chemical sensors, including electrochemical, optical, and other types of sensors, with a particular focus on applications in process and environmental monitoring within aquaculture. Examples will be relevant to aquaculture, especially RAS (Recirculating Aquaculture Systems). Various sensor systems covered include electrochemical and optical pH sensors, salinity sensors, different types of ORP (Oxidation-Reduction Potential) sensors, and sensors for various gases such as dissolved oxygen, CO₂, and H₂S. Furthermore, the course addresses other ion-selective sensors and general sensors for monitoring selected ions (ammonium, nitrite, nitrate, calcium, and metals). Alternative methods for analyzing these parameters are also explored, and the module discusses the advantages and disadvantages, as well as calibration and maintenance of sensor systems.

Learning outcome

After completing the module, candidates should be able to:

• Explain the principles behind various sensor systems used in aquaculture (e.g., pH, oxygen, CO₂, ammonium, etc.).
• Understand the use of electrochemical and optical sensors in water quality monitoring.
• Carry out quality assurance, including basic calibration, maintenance, and other quality control steps to ensure good quality in sensor measurements.
• Assess the advantages and limitations of using different sensor technologies.
• Interpret real-time data and use it to support decision-making in operations and production.
