Biosystems Instrumentation is becoming more and more important for PhD students of different disciplines not only from technology related. In Scandinavia the PhD education but also the research in general is often on high technology level due to the need for environmental monitoring. Having followed the course the students will understand principles and limitations in using measuring and sensing systems as well as data processing methods. Sensing systems will be described, demonstrated and applied as tools for scientific research within agriculture and related areas. The students will achieve a deeper knowledge about measuring principles, selection of equipment and data processing systems. They will also achieve qualifications to judge results with regard to credibility and accuracy.
