Aims

The aim of the course is to familiarize students with the basic theories, principles and modern design of sensors of physical quantities and provide knowledge for the design and optimum utilization beyond the bachelor's course BMFV. Furthermore, they present the basic problem of sensor technology (parasitic effects, calibration, diagnostics, etc.) and their elimination. The main goal of this course is engineering knowledge of the fundamentals of sensor technology (IT) physical quantities, which represent the industrial and scientific practice, at least 93 % of all measurements.

Specification of controlled education, way of implementation and compensation for absences

Laboratory is compulsory, properly excused absences laboratory exercises (maximum of two) can be arranged with the teacher substitute (usually in the credit week). Specification of controlled education, way of implementation usually provides annual public notice.
