CHAPTER I

INTRODUCTION

1.1 Project Introduction

Wireless Data Logger is a device which enables collection of particular data from distinguished sensor to be sent to a personal computer or a laptop via wireless transmission medium. In this project this device incorporates the use of Bluetooth with the range of 30m indoor and 100m line of sight outdoor to send the information from time to time to a data logging framework software. Moreover the device as well will be included with Liquid Crystal Display (LCD) panel to provide real time monitoring of temperature and humidity on the device as well. The information collected as well will be compiled into a spreadsheet with the help of the data logging framework software. Typically data logger is battery powered and includes a sensor, microprocessor, wireless medium and computer interface.

(17)

2 1.2 Project Objectives

The main objectives of this project are to design and construct a wireless data logger which is relatively cheap in cost which is estimated to be around RM250 below with minimizing components to achieve its economical value. Moreover it is also to use Bluetooth as a module in providing wireless transmission medium to transmit information to a Bluetooth enabled personal computer. It is also to use Microsoft Visual Basic software to design a data logging framework which will collect data wirelessly and convert the data into spreadsheet to be analyzed later on.

1.3 Project Problem Statement

As mention above in the introduction, this system uses wireless communication system as transmission medium as previous data loggers do require wired transmission medium to communicate. Nevertheless the development is not limited until that, whereas extra features can be installed in this project that will provide a convenience to the user.

By implementing Bluetooth technology allows remotely to access and use Bluetooth enabled devices without the use of wires. In this case the device can be moved around easily without the need of altering wires plus with a limited range. However the Class 2 Bluetooth will be used as it can provide the range of 30m from the interfacing personal computer or laptop.

Compare to the previous project, the wireless data logger was not included with real time monitoring. Real time monitoring via LCD as well provide the user with ease of application. Real time monitoring as well will enable user to determine whether the device is functioning with perfect as well the information being monitored on the spot to enable any configurations to be done on the environment by the user.

This device as well will be featured with temperature and humidity reading with the help of distinguished sensor. Plus this information will be transferred to a

(18)

3 personal computer or a laptop with the help of data logging framework thus converting the information to a spreadsheet for further analysis by user .This project is being developed with low cost and for simple installation as most already available data logger in the market are expensive as well as complicated to be used.

1.4 Project Work Scope

On the other hand, for the software part it includes the development of data logging framework as control panel to receive information via Bluetooth. The software for the data logging framework will be developed using Microsoft Visual Basic. Thus as in software the programming of the PIC as well will be done by using MPLab. Personal computer with enabled Bluetooth will then be interfaced with the Wireless Data Logger device.

The scope of this project basically divided into two parts which is hardware and software. For the hardware section, the designing of the wireless data logger prototype consists of only one type of sensor component which can sense changes in temperature and humidity , programmable microcontroller (PIC) and Bluetooth module which need to be configured first before it can transmit information wirelessly to Bluetooth enabled personal computer or a laptop. The PIC which is being used is a 16F887 PIC where it is programmed to interface with software. Thus the designing of it continues with fabrication of the printed circuit board (PCB).
