WSN sensors for precision agriculture

The application of technology in the field of agriculture has increased the effectiveness and efficiency of the farmers. The application of Wireless Sensor Network (WSN) in precision agriculture assists the farmers to know about their fields in statistical manner, which helps them in making better and accurate decisions. There are various type of sensors that can be used to calculate the statistical parameters of an agricultural fields, which convert the event or a phenomenon into an electrical or measurable quantity. This paper provides an elaboration of the basic principles of some of the sensors and their related specifications of few commercial products.
