Wireless Sensor and Actuator Network(s) and its significant impact on Agricultural domain

In context to advancements in technologies, there exist a variety of sensors that are incorporated within the fields for obtaining vital as well as auxiliary information. Among various areas of implementation for Wireless Sensor Networks (WSN), agriculture is one such domain that has experienced revolutionary advancements over the past few years. Favorable outcome for agricultural practices completely depends on correct identification and selection of sensor. In order to administer the agricultural issues in today's date, deployment of sensors has become a necessity within the domain. The basic vision of this research article is to shed light on various agricultural sensors that are available in today's date followed by proposing a framework that suggests the precise amount of fertilizer requirement by the field after accessing various associated parameters. The study proposes Requirement Based Decision Support System (R
_b
DSS) after evaluating various parameters, i.e., Soil moisture (Sm), Soil temperature (St), Soil humidity (Sh), Volumetric Water Content (VWC), and Electrical conductivity (EC). The results of the experimentation depicts decrease in the consumption of fertilizers by 24.68 %.
