Design and implementation of a wireless sensor and activator network for urban garden irrigation systems

Abstract - The implementation of micro-irrigation in urban gardens is being more popular over the years. But, after the initial installation of such micro-irrigation systems, it makes some inconveniences and discomforts in order to control it manually. Considering all the aspects of the issue, deployment of wireless sensor and activator network (WSAN) can be the most optimal and comprehensive solution. Nonetheless, employment of wireless sensor and activator networks in urban irrigation sector poses different difficult tasks, such as longer battery life, sufficiently long range capability, compact size volume and low cost simultaneously. In the recent past, several different technologies have been used to solve those challenging tasks. In this thesis project, wireless Zigbee network has been studied and analyzed. This work proposes a simple, compact and cost effective design of WSAN specifically to control micro-irrigation of urban gardens. This thesis project presents designs and implementations of hardware and software for the wireless sensor and activator network nodes and coordinator.
