Wireless sensor network for flexible pH array sensor

Abstract

In this study, a wireless sensor network (WSN) for flexible pH array sensor has been developed by virtual software of National Instrument (NI) Laboratory Virtual Instrument Engineering Workbench (LabVIEW). The measurement data were received from measurement node and sent to a gateway connecting with computer through WSN. The WSN has been combined successfully with flexible pH array sensor. And the sensitivity and linearity of the flexible pH array sensor received through WSN are 53.39 mV/pH and 0.990 in pH concentrations between pH1 and pH13 at room temperate (25°C), respectively. Therefore, the developed WSN can be applied to the flexible pH array sensor practically. © 2011 Springer-Verlag.
