Lord Kelvin, the 19th century mathematical physicist and engineer, is famously quoted as saying: "If you can not measure it, you can not improve it." He has been proved right, of course, but even he could not have predicted the advances in metrology, the science of measurement, with wireless data acquisition (DAQ) being one of the most rapidly evolving technologies today. Where a wired approach can present logistical and cost-related problems, such as when accessing remote locations or crossing roads, wireless DAQ offers an alternative. With a protocol such as Zigbee, for example, each measurement node can communicate wirelessly to other nodes and, via an Ethernet gateway, to a PC. Link
