2018 Portland State University Students Capstone students were posed with this project.

Data acquisition (DAQ) is the process of measuring an electrical or physical phenomenon such as voltage, current, temperature, pressure, or sound with a computer. 

The Continuous Solutions machine testbed DAQ system consists of sensors, analog-to-digital converters, filters, and a single board computer (SBC) server. 

The EVM used to interface with a variety of analog and digital sensors, providing both primary and secondary motor characteristics to gather and collect data on Continuous Solutions’ 100 kW testbed. 

The timespan for this project was a total of 6 months, with five distinct milestones. Each milestone completion was necessary before moving on to the next phase.
