A design of a remote weather factors monitoring system

Abstract

Wireless sensor network become the most important part in any technology that need to monitor the environment. One of the new trends that need wireless sensor network is military applications. Some of the previous studies used Bluetooth module to send the measured weather factors wirelessly from the weather factors monitoring system to the central station. The problem of using Bluetooth module is limited range of it (10 m at one mill watt transmit power). Moreover, some measured weather factors expose to errors especially if these factors depend on critical events like missing missile target, which lead to loss in human and expensive material. The main objective of this paper is to overcome these problems by designing accurate monitoring system and use X-bee wireless communication module that operate within 2.4 GHz frequency band. The design consists of three sensors nodes and central station. The methodology includes three steps. Firstly, every sensor node read the weather factors several times. Secondly, the sensors nodes send these measured weather factors to the central station wirelessly using X-bee module. Lastly, the central station calculates the average of the received measured weather factors to get accurate results, then store these results in a database and display it in monitoring system. The design is more accurate and very simple. This paper recommends that using a wide range of wireless communication module between sensors nods and central station.
