Abstract
This project is to design and implement a reconfigurable measurement interface for Internet of Things sensors, for the Microelectronics Department of the Delft University of Technology. This thesis will discuss the functionality and design process taken in designing such a reconfigurable measurement interface, focusing on generating signals and control control signals for the hard- ware. The important choices will be highlighted and the strengths and weaknesses of each design choice will be weighed in order to produce a fully functional measurement interface. In the span of 10 weeks this group was able to successfully generate sinusoidal, square, and triangular waves as well as DC voltages at +12V and +24V and in the voltage range of -10V to +10V on different pins of the dip-48 socket. Sensor output voltages can also be measured and observed using an external computer.
