ZigBee Based Wireless Sensor Network in Precision Agriculture - The Survey

ABSTRACT A WSN is a collection of micro-electro-mechanical devices. These devices have wireless receiver and transmitter technology, computational processing ability, and a power supply [12]. In a WSN large number of sensor nodes usually span a physical geographic area. The main purpose of sensor node is to monitor and control the environmental parameters as per the crop requirements. Wireless sensor networking is gaining popularity for managing precision agriculture through real-time monitoring of agricultural parameters and climatic conditions. Using Clustering and data routing algorithms in Wireless Sensor Networks nodes can be deployed and managed in ubiquitous applications like precision agriculture and many more. This paper investigates a remote monitoring system using ZigBee. Data is sent wirelessly by sensor nodes to a central server, which in turn stores it and will allow it to be analyzed [9].
