2. 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. Energy saving using microcontroller

4. AUX POWER:  230 AC voltage is given. LED:  Three LED are used and one blinking LED is used.  Blinking LED is used for day-night sensor.  Other LEDs are connected to object moving sensor. SENSORS:  Three IR sensors and one day-night sensor is used.  IR sensors sense the moving object, while day-night sense the light. MICROCONTROLLER:  At89s52 micro controller have to used in this project this with special function driver.  At89c52 is low power, high microcontroller CMOS 8-bit microcomputer with 8K flash erasable and programmable flash memory.

7.  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.

8.  System is automatic hence you don’t need manpower for giving signal and human errors are eliminated.  System is reliable hence you can depend on working of the project.  The system based on microcontroller hence external components are minimum.  Low cost system, providing maximum automation.

9.  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.
