Educational data acquisition system with USB interface

Data acquisition systems have become widely used tools in science and technology school laboratories. Their capabilities together with an inclusion of sensors and actuators enable teachers to perform a variety of experiments with an important didactical value as a part of a pedagogical process. This paper presents a USB based data acquisition system aimed at fulfilling the requirements of a broad spectrum of laboratory situations. It was developed according to a decade of experiences in providing computer aided laboratory courses at a high school and faculty levels of education.
