Wireless Sensor Network for Farm Field Automated Drip Irrigation for Coconut

In any good crop production, timely irrigation and demand-based water supply is very important. In this paper, we propose the conceptual design of an automated irrigation system for Palm trees, especially coconut trees. In Southern part of India, climate is more suitable for Coconut crop. In non-coastal areas where water is a scarce resource, automated drip irrigation is found to be a better solution. Various sensors like GPS (Global Position Sensors), soil moisture, temperature and climate are used to calculate site-specific, real-time irrigation requirement using Penman Monticth water demand model.  In our design, palm trees are placed at every edge and middle of regular hexagonal structure which increases the coverage area of the Zigbee communication and reduces the installation cost compared to traditional square spacing.
