Design and Construction of a Low Cost Digital Weather Station

Abstract

This work is focused on the design and construction of a low cost weather station which makes weather related data available for different purposes such as agriculture, aviation weather forecasting, etc. The design is made up of an outdoor module which measures four weather elements (temperature, atmospheric pressure, relative humidity and wind speed) through their respective sensors. This module transmits the sampled data wirelessly through radio frequency (RF) to an indoor module which receives the data and automatically logs the data to a database. A MATLAB® based graphical user interface (GUI) was also incorporated to view the logged data and perform some setup operations on the system.
