Indeed, Wireless Sensor Network (WSN) is an ubiquitous field, exhibiting wide application potential for electronic management of data of Site Specific and Temporal Variability (SSTV). Emphasizing real time monitoring of an indoor environment of textile industry, the WSN of five sensor nodes (SN) has been designed and by employing suitable wireless communication protocol, it is established to monitor relative humidity and environmental temperature of textile industry. The salient features of the

... SN decide reliability and preciseness of the WSN. Employing an embedded technology, the wireless sensors nodes have been designed, wherein ARM microcontroller, ARM LM4F120H5QR, is used as a core for computational task. To facilitate wireless networking the Zigbee technology is availed, wherein the transceiver modules, Xbee series-2, have been incorporated. Typically, two sensors, humidity sensor (SY-HS-220) and temperature sensor (LM35), are interfaced, with suitable analog electronics, to the Sensor Nodes. Present sensor nodes have designed to follow IEEE 802.15.4 standards. Being a measuring instrumentation, the sensor nodes have been scientifically calibrated to the real units and standardized with sophisticated instrument as well. The Refinement factors (R) are optimized and resulting empirical relations have been incorporated into the firmware. The parameter values shown by the sensor nodes and that of obtained from the standard instruments found close match. This reveals the reliability and accuracy in the co-design of hardware and firmware. Deploying an IDE X-CTU, the SN have been configured for dedicated responsibilities such as End Devices (ED), Coordinator (C) and Router (R). The Wireless Sensor Network under investigation, for realization of on-site implementation, is established in the indoor environment of textile industry. Instantaneous values of parameters are recorded, in real time, in the dedicated data base and demonstrated on smart GUI of the Base Station as well. Results of implementation support the deployment of present WSN for industrial applications.
