Mobile devices are becoming more powerful, reliable and common every year. Hence we can use mobile devices for conducting laboratory sessions in distance education. This paper discusses issues of integrating Short Message Service (SMS) to operate instruments of hardwarebased remotely triggered laboratories. Components of the system include searching an experiment, performing experiment, result handling, error handling and method of exchanging information. It is designed using the National Instruments (NI) Laboratory Virtual Instrument Engineering Workbench (LabVIEW) development system and web services. The scheme will enable students to conduct hardware experiments with mobile devices using SMS from anywhere and anytime.
