Sensor systems are courses that discuss the basic principles of measuring physical quantities, characteristics of sensors, signal conditioning circuits and sensor interfaces, working principles of sensors (motion sensors: measurement of position, speed, acceleration; optical sensors, thermal sensors, acoustic sensors, and pressure sensors ), how to characterize and calibrate the sensor. Learning is carried out using discussion methods and project based learning (creating a project in the form of a simple measurement system using sensors complete with system calibration and characterization).
