Study on wireless intelligent surface acoustic wave CO gas sensor based on grid computing and Web service

Surface acoustic wave (SAW) gas sensors based on PANI (polyaniline) is studied experimentally and theoretically to overcome the Low sensitivity, high working temperature and high cost of the traditional CO gas sensors. The sensor networks system required that sensors have some function of Grid computing. In this paper, we discuss a model for interfacing sensors to grid computing and show how to use embedded Web service technology, ARM9 microprocessor, embedded Linux, embedded service toolkit SOAP implement intelligence and grid function of sensor. Fast response and recovery time with good repeatability were observed at room temperature.
