A Real-Time Wireless Sensor Network Based on 802.15.4/ZIGBEE to Control Home Automation Environment

Greenhouse facilitates precise monitoring and con-trolling of various parameters, so as to cultivate quality con-science crops without slaying resources. The cabling laid for the sensors, deployed inside the Greenhouse is not feasible. Hence the need for an automated system employing wireless communication and remote sensing is imperative. This paper proposes a Wireless Sensor Network (WSN) based embedded system and deals with the implementation of ZigBee network (over IEEE 802.15.4) for remote controlling of the Greenhouse parameters. The detailed information regarding establishment of ZigBee network in Star topology as well as in Mesh Topology, inside the Greenhouse is illustrated. It also demonstrates the real time monitoring of parameters such as temperature, humidity, as well as the total power consumption of the system, with the help of a PC based GUI application developed on Java platform.
