ELECTRONIC EYE WITH SECURITY SYSTEM
DESCRIPTION:
The major action in this system is controlled by transmitter section; this section consists of IR transmitter and IR receiver and RF transmitter .and Here we need to generate IR frequency continuously, so that by using a small tiny micro controller frequency is produced and is connected to the IR led to generate IR light rays of 38 kHz frequency.
IR receiver continuously receives the signals from the transmitter .when ever the light path in between IR transmitter and IR receiver cuts by an Obstacle, receiver signal gives low to high pulse.
By connecting the receiver output to the micro controller interrupt pin, it gives interrupt to the micro controller. Immediately the system gives the buzzer and sends the message to the remote location by using RF transmitter. RF receiver is tends to display the message on LCD display by connecting it to the micro controller
COMPONENTS:
• AT89S52
• AT90S2313
• LCD DISPLAY
• TLP434
• RLP434
• IR LED
• IR RECEIVER
SKILL SET:
• Embedded ‘c ’ programming
• Functionality of all above components
• Rf communication concept
• Micro controller working principle
