At this time, sensor developers rely on their own circuit board designs to test new sensors. This means a lot of time and money is spent on designing the custom interface for every newly designed sensor. This report describes a way to have a configurable test bench for sensors. The system consists of a data acquisition unit and multiple circuit boards to be able to have a certain level of reconfigurability for the used pins. This system is also able to generate simple signals. It is therefore a replacement for certain instruments as well. The test bench has 9 configurable pins and a number of external connections. It is simple to use and can do its job automatically. This report focuses on the hardware part, where all the switching and amplification is done. We recommend to use the system on a trial basis, because it is not completely functional yet.

Design and fabrication of a measurement interface for smart IoT sensors
Signal generation and hardware control
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.
