THURSDAY, 12 APRIL 2012 (PRESENTATION PROPOSAL FINAL YEAR PROJECT)

During this week we are required to do the slide show and present the project to the assessor. My first assessor is Mr Ismail Adam but he not there so it is replace with Dr Khairil and the second assessor is Miss Nurul Fazlin Roslan.

TUESDAY, 3 APRIL 2012 (CONCLUSION & REFERENCE)

CONCLUSION

The study of ultrasonic is very interesting. Although the discovery of ultrasonic began long time ago, but it’s secret still never ended and always been researched from decade to decade. To achieve the objectives of development an ultrasonic rat’s repelled, the ultrasonic communication upon the rats had been studied. The main objective of this project is to develop more efficient product of electronic rat repellent. The method of completing this proposal is an internet research in literature review and some book that give idea to develop this project. All this knowledge will help about next steps for carry out this project in next semester. This project will include a certain technology which is wireless communication using radio frequency of receiver and transmitter of 315MHz. Practically the target user is all the people in the home and the food stores that contain many rats as you see. So this product is suitable for the food stores in order to chase the rat away for our area because the rat can harm the human. Now, there are many people die because of the rat. The rats contain many diseases that will affect the human health. This project is to develop the current product in real life now to be more efficient and effective in order to drive away the rat.

WORK PLAN

The duration to complete the final year project is divided into two semesters. For semester 1 is for the proposal and semester is for completing the hardware. The Gantt chart for the project is shown as in Table1 below:

TUESDAY, 13 MARCH 2012 (METHODOLOGY)

METHODOLOGY

From the block diagram, the operation start when the rat detect by the motion detector. Then the signal is send to the main unit in order to On the Ultrasonic circuit at the small unit. The rat is chase away by the Ultrasonic sensor that produces 30KHz to 60KHz of the frequency. This frequency only the rat can hear and cannot harm the human being.  This product is use a transmitter and receiver to send the signal and receive the signal. For this transmitter and receiver, Radio Frequency (315MHz) is use. This study will review the reaction of the mouse when the Ultrasonic circuit is switch ON. Electronic components have played an important role in the ultrasonic rats repelled. The ultrasonic circuit will be impossible to implement without the electronic components. Therefore, in this project the several components have been used such as ultrasonic sensors, ICs, transmitter, speaker, indicator and basic components like capacitors and resistors.By doing the small unit it can save energy because the system only ON when it detect the movement of the rat. Then the main units active the ultrasonic circuit to produce high frequency after get signal from small unit. The ultrasonic circuit is at the small unit. It only ON after detect the movement of the rat. 

FLOW CHART

From the flowchart, the process of rat repellent is start when the small units detect the rat by the motion detector sensor. This system must be powered ‘ON’ for supplying the sensor, microcontroller, receiver and the transmitter. It will begin when the rat is detected by the motion detector and then the RF transmitter sends the signal to the main unit. Next the main unit is receive the signal by the RF receiver and the microcontroller ON the ultrasonic circuit at the small unit and drives away the rat at the area. The timer is setting to on and off the ultrasonic circuit in order to save the energy.
