WEEK 5

This week I continue the design of Receiver Circuit. There are two type of circuit for my project and it use RF 315 MHz to transmit the data and receive the data.

WEEK 4

For this week I want to design a circuit for ultrasonic repellent by using Protel DXP 2005. Need to be careful because after design I want to do the skeching schematic diagram on the board. This week I design for Transmitter circuit. Below is my schematic after finish drawing:

WEEK 3

For this week buy all the component needed for the project and test it. Need to check all the component whether it is function or not. Below is a few picture of my component:

WEEK 2

This is my new block diagram of the rat repellent. It change a little bit from the previous that I have propose on the proposal but the flow is still same. Below is the diagram:   

Project Description

• Rat repelled is using transmitter 315 MHz and receiver 315 MHz module to send and receive data. Transmitter module and receiver module is operating using adapter as power supply. This system is using PIR motion sensor to detect object motion and computer interfacing send data to computer.

• When system is operating, PIR detect object motion. If object detected, system generate 40 KHz output to multimedia speaker. Transmitter will send the data to receiver, blue LED will blink. After 10 seconds, system will stop output to multimedia speaker.

• Receiver module detects data from transmitter module. If data detected, LED will blink and system will send the data to computer.

• Computer will initialize serial port and detect data from PIC. If data detected, system will store the data in computer and show it on screen.

FYP SEMESTER 2 (WEEK 1)

Opening a new semester and semester 2 for a final year project. For this week I only listed the activity that to be done in this semester until at the end of the semester. Then I prepare the final process before I do the project. I make schedule for this semester in order to make the project to be done on the time.
