Introduction: -
Aim of the project is to sense moving object passing from three IR sensors.
Three sensor are used to sense the moving object and lights are turned ON.
AT89s52 micro controller is used with requirement of project.
Energy can be saved if properly implemented.
FEATURES OF AT89S52
• Compatible with MCS-51® Products
• 8K Bytes of In-System Programmable (ISP) Flash Memory
– Endurance: 1000 Write/Erase Cycles
• 4.0V to 5.5V Operating Range
• Fully Static Operation: 0 Hz to 33 MHz
• Three-level Program Memory Lock
• 256 x 8-bit Internal RAM
• 32 Programmable I/O Lines
• Three 16-bit Timer/Counters
• Eight Interrupt Sources
• Full Duplex UART Serial Channel
• Low-power Idle and Power-down Modes
• Interrupt Recovery from Power-down Mode
Description of circuit diagram
AC 230v is given to circuit.
Three sensors and one day-night sensor is connected to resistor.
12MHz crystal oscillator is used.
7805 voltage regulated IC.
Three LED and one blinking LED is used.
CONCLUSION:
From this project we conclude that energy can be saved if worked properly.
This project can be implied to many public places where rush is less during night.
No self-test system to detect malfunction of sensors.
Requires uninterrupted power supply.
