1st Semester, A.Y. 2014-2015CHAPTER 1: THE PROBLEM AND ITS BACKGROUNDThis chapter presents the background of the study, its conceptual framework, the problem and its significance, and the scope and delimitation of the study.1.1 IntroductionIn the 21st century, weather monitoring holds great importance and have uses in several areas ranging from keeping track agricultural field weather conditions to industrial conditions monitoring. Weather monitoring would help in keeping track of different climatic behaviors including temperature, humidity, and light intensity. A weather monitoring system can be either wired or wireless. In case of wireless communication, the connectivity will be more convenient and user friendly and weather monitoring would not require physical presence of the person at the location. Wireless communication is the transfer of information over a distance without using wires. The distances involved may be short (a few meters as in television remote control) or long (thousands or millions of kilometers for radio communications).GSM technology is the cheapest and the most convenient technology now being used for wireless communication. The wireless weather monitoring system basically requires few modules such as a GSM module, sensors and microcontroller module.

1.2 Conceptual FrameworkThis study aimed to design and construct an automatic weather monitoring system to make weather monitoring easier. Figure 1 shows the conceptual framework of the study.Tipping Bucket Rain GaugeARDUINO MEGADATA LOGGERWind Vane -Anemometer

1.3 Statement of the ProblemThis study aimed to design and construct an Automatic Weather Monitoring System. In doing this, the study had the following specific objectives:a) To design and construct a computer-based, sensor-operated rain gauge, anemometer and wind vane that can measure weather data accurately. b) To create a computer application capable of updating its weather database on a daily basis, and also display the real time measured data.c) To store the measured data in a data-logger so as to enable the user to fetch data whenever a complete log is required. 1.4 Significance of the StudyThe large utility of the wireless weather monitoring in varied areas ranging from agricultural growth and development to industrial development takes much significance of conducting this study.The weather conditions of a field can be monitored from a distant place by farmers not needing them to be physical present in the area for them to know its climatic condition. To cite for an example, it would be of great use in the war affected regions as it would be too risky for farmers to visit their farm regularly as it would enable them to monitor their farm from their home.1.5 Scope and DelimitationThis study is delimited to the design and construction of a microprocessor and sensor based weather station that can transmit measured weather data wirelessly.Furthermore, it would conclude with the testing of functional prototypes and the determination of the conditions necessary for the device to be economically feasible.1.6 Definition of Terms Aerovane It is used to measure both wind direction and speed. The tail orients the instrument into the wind for direction while the propellers measure the wind speed. DBMS- Database management systems(DBMSs) are specially designed software applications that interact with the user, other applications, and the database itself to capture and analyze data. GSM- (Global System for Mobile Communications, originallyGroupe Spcial Mobile), is a standard developed by theEuropean Telecommunications Standards Institute(ETSI) to describe protocols for second generation (2G) digitalcellular networksused bymobile phones. Mobile Phone A mobile phone (also known as acellular phone,cell phone,hand phone, or simply a phone) is aphonethat can make and receivetelephone callsover a radio linkwhile moving around a wide geographic area. It does so by connecting to acellular networkprovided by amobile phone operator, allowing access to the public telephone network. Precipitation - Inmeteorology,precipitationis any product of the condensation ofatmosphericwater vaporthat falls under gravity. Rain Gauge - Arain gauge(also known as anudometer,pluviometer, or anombrometer) is a type of instrument used bymeteorologistsandhydrologiststo gather and measure the amount of liquidprecipitationover a set period of time
