Smart irrigation technology for efficient water use

Abstract

The importance of water resource does not need to be proven. At first sight water seems to be the most abundant resource on earth, but in fact freshwater represents only 1% of all terrestrial water, and the remaining 99% are not available for human use. Of all economic sectors, irrigation is the sector where water scarcity has the greatest impact. Currently it is the largest consumer; it is also the sector with the most adjustment possibilities by integrating intelligent technologies such as wireless sensor networks (WSN) to guarantee more precision in the consumption of this vital resource. However, sensors have limited energy capacity; to resolve this problem in the presented proposal; solar energy is used to power the system. The aim of this paper is to explain how to implement wireless sensor networks technology and solar power in the irrigation field, the most used standards and technologies associate this implementation.
