Android Based Water Deployment System for Irrigation using WSN & GSM Module

The aim of this paper is to design a water deployment system for irrigation which is based on the combination of embedded system and low power ZigBee wireless communication technology for system automation & monitoring. The system has a distributed wireless network of soil-moisture, humidity and temperature sensors placed in the root zone of the plants. The wireless sensor network consists of two main units Wireless Sensor Unit (WSU) and Wireless Information Unit (WIU). Real time data is collected by wireless sensor unit and transmitted to wireless information unit using ZigBee. Data is received, identified, saved and displayed at wireless information unit to achieve soil moisture, humidity and temperature monitoring. The data is continuously monitored at wireless information unit and then it is transmitted on the android smart phone through GSM (Global System for Mobile Communication) module for controlling actions. The main objective of the work is to simplify the method of irrigation using android smart phone. The implementation of system hardware and software are given, including the design of wireless node and the implementation principle of data transmission and communication modules. This system helps the farmer to save water as well as reduce effort of the farmer and has the advantage of efficient monitoring, highly sensitive, feasible and simple to design and install.
