Abstract

This thesis is part of the development of a sensor system for measuring currents in the Nuna solar car. A big problem within this system is the processing of incoming sensor data. Therefore, a solution in the form of a sensor-data-processing-unit was proposed, with its primary focus on the analog-to-digital conversion. The converter should not act as a bottleneck on the quality of the analog input. An accuracy of 62.5µV was achieved, which complies with the minimum requirements. The analog-to-digital converter's analog sensor input, ranges from +2.048V to -2.048V. Additionally, a sensor-detection system is introduced. All in all, the minimum requirements are met, but there remains room for improvement.
