Abstract: Main reasons for the global water crisis besides population growth, urbanization, and climate change are excessive water use, poor management, and inadequate irrigation. According to the United Nations World Water Development Report, 70% of freshwater worldwide is used for irrigation. The amount of applied water does usually not match the requirements of the irrigated crop, and either too much or too little water is used for irrigation. To enhance the resource utilization in a constrained manner an autonomous sensing platform is developed, where a number of wireless sensor nodesare installed in an agriculture land. Weproposed a system with three wireless sensor nodes by the exploration of “mesh network” to cover large area. Wireless sensor nodes observes the environment, samples and collects the heterogeneous data like soil moisture, temperature, from the interested field and transmits data to the server.A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It is also a form of wireless ad hoc network. When one node can no longer operate, the rest of the nodes can still communicate with each other, directly or through one or more intermediate nodes by using ZigBee and data of that node is transmitted to main server.
