Remotely accessible laboratory for instrumentation and sensors

This communication describes a project developed at the Technical University of Catalonia (UPC) in Barcelona, Spain. The goal was to solve the trade-off between the need for performing real laboratory practices in engineering education and the emergent implantation of distance learning in our curricula. Most of our courses in electronic engineering have 50% of the load devoted to laboratory work and our aim is to avoid a reduction of the lab charge and its substitution by virtual labs based only on simulation. The subjects of the experience are the instrumentation and the sensor laboratories. The solution developed was a remote workbench, based on a web server, a set of controlled instruments and several circuits, sensors and actuators connected to the instruments through a switching matrix. Control and user interface software was developed using LabView 6.1, and Perl routines were used to provide access control and system protection.
