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.
