FINAL YEAR PROJECT 2 (WEEK 4): Vibration Sensor Testing

Objectives:

1) To construct circuit of vibration sensor.

2) To test the functional of vibration sensor.

Method:

1) The circuit that had been constructed based on Cytron website.

Conclusion: It can be seen that the vibration sensor is function when gives an impact to it. The LED on when the vibration sensor is vibrate. The vibration does not have any polarity so it easy to get use of it. 

FINAL YEAR PROJECT 2 (WEEK 3): Temperature Sensor Programming

Objectives:

1) To construct circuit of temperature sensor and display the value on the LCD.

2) To build a program using C++ language 

Method:

1) using Proteus 7 Professional software to construct circuit

2) using KeilVision4 to write the program

The program has been written and compiled. The HEX file is loaded to the circuit. The simulation is running to demonstrate the system operation. Below is the circuit which had been running the program:

When the temperature is at high, the temperature value is increase and vice versa. The program need to be adjusted as I just tried by myself to do this program besides refer to notes and websites. 

Conclusion: 

This week I learn how to do the program for temperature sensor which linked with the LCD display. I learned that the program need to start by declared the input pins that had been used in the circuit. To display the value on the LCD display, we need to do HEX value to ASCII code conversion and then do the conversion of the DEC to ASCII.

FINAL YEAR PROJECT 2 (WEEK 2): LCD Display Programming

Objectives:

1) To construct circuit of  LCD display.

2) To build a program using C++ language 

Method:

1) using Proteus 7 Professional software to construct circuit

2) using KeilVision4 to write the program

The program has been written and compiled. The HEX file is loaded to the circuit. The simulation is running to demonstrate the system operation. Below is the circuit which had been running the program:

Conclusion: 

This week I learn how to do the program for  LCD display. I learned that the program need to start by declared the input pins that had been used in the circuit. To display the word or character on the LCD display, we need to know the position of the character based on the LCD command codes table. The LCD pins also plays an important because if it not connects well to the microcontroller, it will not display the word on the LCD.

FINAL YEAR PROJECT 2 (WEEK 1): Hardware Materials and Budget

 For this semester, the hardware material of this project need to buy to implement this project. Firstly, we need to find the hardware materials and compare the prices to buy it. The project materials are:

• Microntroller AT89S52
• Vibration sensor
• Alcohol sensor
• Pressure sensor
• Temperature sensor
• LCD Display
• GSM Module
• GPS Module
• ADC 0809
• RF Module
• Helmet

The budget for this hardware material is at around RM500. So, these are the budget of each components that had been searched below:

No.	Item	Price (RM)
1	Microcontroller AT89S52	10
2	Vibration Sensor	20
3	Alcohol Sensor	22
4	Pressure Sensor	90
5	Temperature Sensor	4
6	LCD Display	12
7	GSM	65
8	GPS	120
9	ADC 0809	17
10	RF MODULE	46
TOTAL		406

   As for me, I hope the project budget is not overlapped and I hope all these should be enough to implement my project. I will be continue to do this blog as it is my log book which can be as my reference when doing this project.
