Low-cost open-source multifunction data acquisition system for accurate measurements

Engineers and scientists commonly use data acquisition hardware and software to research unknown characteristics through measurement and analysis. Computer-based data acquisition systems are a powerful, flexible, and cost-effective measurement solution. This paper presents the hardware and firmware design of a low-cost computer-based data acquisition system that can be very interesting for conducting laboratory experiments and industrial applications. Its open-source philosophy opens the door for free software users and developers that would be interested in contributing with the project.
