In the previous era, the technology application mostly using wire but now a wireless device has become common place. The definition of wireless sensor network is an application that having no wires connection on that devices. In addition, to make the system easy to monitor from a distant location, the RF 433MHz module was used. So, this project gave rise to the idea for studying details about the RF 433MHz module performance for WSN application.
1.1 Project Background
Nowadays, using the wireless sensor network (WSN) technology to monitor the environment helps someone to solve the problems of deployment difficulty, high cost, and realized unmanned monitoring which is mostly used in factory, buildings, laboratory and house. This project is to study the range and performance of the RF 433MHz module for WSN application. RF 433MHz module are popular used in remote control system. This range also available to use in this area. There are two types of the RF module which is transmitter and receiver. From research, using RF 433MHz module, the data can get more accurately without any data losses with the range that given than compared to other transmission for wireless sensor network.
The range that can reach by this RF module is different between outside and inside area. For inside area, it can work for 50 meters through multiple walls with an antenna, while for the outside area, it will be able for hundreds of meters. Besides that, a microcontroller such as Arduino also used in this project. Arduino that available for this project is Arduino PRO which is it has 3.3V port that will be easier to connect directly to the types of RF 433MHz module that used in this project.
This project also will be studied the analysis of the data transmission by giving a few of distance between the transmitter and receiver of the RF 433MHz modules when located in the obstacles or line of sight area. Then, the data that are received will be displayed on the computer whether there are data losses or not.
1.2 Problem Statement
The problem that becoming as issues right now is there is a lot of ways to send data but the problem is about the range, cost, and data losses. So, for this situation, study the performance of RF 433MHz can overcome the problem for the WSN application.
The objectives of this project are to understand the range and performance of RF 433MHz module. Moreover, exploration about the transmitting and receiving the data by using the RF 433MHz module.
1.4 Work Scope
The main work scope of this project is to make sure this project will achieve the objectives.
The main focus of this project:-
i. To study and understanding the range of RF 433MHz module.
ii. To transfer data by using RF 433MHz module.
In this project, there are three main parts. For the first part, it will be focused on the conducting the literature review and do some research more detail about the RF 433MHz module. Meanwhile, for the second part, after the software development process, the hardware development process will take over and include the testing of the project. Last part, when the hardware and software complete their part, it will be followed by testing the performance and the operation of the project to make an analysis.
1.6 Report Structure
This part will explain all the flow for completing this report and project. In this report, there are five chapters.
Chapter 1: Introduction
This chapter will introduce the background of the project, state the problems, clear about the objectives, scope of work, planned the methodology and structure of report to make it organized.
Chapter 2: Literature Review
This chapter will be explained more details about all the research that have been done. Then, the summarization for the project also will be attached to this chapter to make it clear.
Chapter 3: Methodology
The methodology is the procedures or steps when doing this project. The simulation, analysis, and evaluation of the project will be discussed in this chapter. This method is important because from here the flow of the process for the project will be updated.
Chapter 4: Expected Results
The expected results in the software or hardware will be stated in this chapter. The comparisons and improvements of this project will be described here. Analysis of the results also will be discussed here.
Chapter 5: Conclusion
In this chapter, to make a conclusion for all the summary of this project was collected in each part can be discussed in the conclusion.
