The advancement of wireless technology is becoming more apparent in industrial sectors with the advent of standards such as WirelessHART. The benefits associated with WirelessHART includes elimination of costly and cumbersome cabling, reduced maintenance cost and reduced deployment, redeployment in the network. However, the current WirelessHART is lack of low cost adapter for monitoring and control application in process industries. In this work, a low cost WirelessHART adapter is developed using a mote and microcontroller (Arduino Mega 2560) for process monitoring application. Experimental results with temperature transmitter shows that the developed adapter is successfully interfaced and the temperature data is monitored continuously at a satisfactory delay. © 2017 IEEE.
