Smart Irrigation System Deploying PSoC and Wireless Sensor Network

Abstract

Traditional agricultural systems require huge amount of power for field watering. This paper deals with designing of a smart irrigation system, that helps farmers water their agricultural fields using innovative technology. There is no need to frequently apply water across entire fields. Instead, they can use the minimum quantities required and target very specific areas. To increase the productivity, the newer technology is more helpful. The important factors of agricultural sectors are temperature, water and fertilizer management. On survey it is found that water management is an important issue, hence the research work is focused on the water and moisture management of soil. In last decades advancements in technology is tremendous. Programmable System-on-chip (PSoC) integrate configurable analog and digital blocks which makes it different from traditional microcontrollers and is a miniaturized device. It combines the architectures of FPGA and ASIC. Deploying the advanced features of PSoC it is proposed to design and develop the smart irrigation system based on PSoC and Wireless Communication Technology. To achieve the desired goal, the data from the soil moisture sensor is processed and the data is calibrated in real units. After that it is displayed on LCD and using wireless technology same is transmitted towards the base station. The smart NRF24L01 transceiver operates on IEEE 802.15.4 Industrial Scientific and Medical (ISM) Band. Moreover, the base station of Wireless Sensor Network is designed to demonstrate collected information in user friendly format.
