Abstract

Recently, due to significant research and development efforts, an innovative field of Wireless Sensor Network (WSN) technologies is evolving as powerful platform for systematically distributed data accumulation and data management. Because of wide application potential WSN is becoming more and more ubiquitous. It ensures the deployment of the technologies such as an embedded technology, wireless communication technology and computer information management technology etc. Emphasizing the themes of Site Specific Crop Management (SSCM), the prime objective of Precision Agriculture, the Wireless Sensor Network is designed and implemented to monitor the environmental parameters of the high-tech polyhouse. The WSN is designed for monitoring of the relative humidity, temperature and intensity of light within the poly house, in the real units. The WSN under investigation comprises ten WSNodes, routed through star networking protocol. The WSNodes are the intelligent devices, wherein the embedded technology is realized. The Hardware is designed about AVR microcontroller, wherein the standards laid down by the IEEE 802.15.4 are emphasized. To ensure wireless networking, the Zigbee devices have been employed, which are configured by the methods suggested by the Digi Corporation. The Base Station, an inherent part the WSN, is also developed and made smarter by developing the Graphical Users Interface (GUI) is dedicatedly developed in the VB environment. Therefore, to realize the monitoring of the domain-wise data of spatio-temporal variance, the WSN is established in polyhouse of smart infrastructure. The results of implementation reveal the facets of Precision Agriculture. On comparison with the standard WSN from Hanback Electronics, it found that, the WSN under investigation exhibit good reliability and preciseness.
