Web-Based Data Acquistion System using a 32 bit Single Board Computer and GNU/LINUX

Most of the previous research in Data Acquisition System (DAS) had used Personal Computers (PCs) as hardware platform which were bulky and not portable. In this research, a Portable Embedded Sensing System (PESS) has been developed using commercial off-the-shelf (COTS) embedded system. Current COTS...
