Optimum Energy Management System
Optimum Energy Management System Abstract: This application keeps the database of the number of persons entering as well as exiting. 555 timer driven 38 KHz signal from IR LED gets interrupted on to the IR receiver to sense the person entering as well as exiting which is fed to a 555 timer. The output of 555 timer is fed to the Microcontroller for analyzing and control purpose

Optimum Energy Management System Introduction: ďƒ˜ The project is designed to monitor the number of persons entering as well as exiting a room. Electrical loads are switched ON as the first person enters and switches OFF when the last person leaves. IR sensors used in combination with microcontroller to monitor all the operations. This helps in saving lot of energy.

Optimum Energy Management System IR LED: An IR LED, also known as IR transmitter, is a special purpose LED that transmits infrared rays in the range of 760 nm wavelength. Such LEDs are usually made of gallium arsenide or aluminum gallium arsenide. They, along with IR receivers, are commonly used as sensors. The appearance is same as a common LED. Since the human eye cannot see the infrared radiations, it is not possible for a person to identify whether the IR LED is working or not, unlike a common LED. http://www.edgefxkits.com/
Optimum Energy Management System BC547: The BC547 transistor is an NPN Epitaxial Silicon Transistor. The BC547 transistor is a general-purpose transistor in small plastic packages. It is used in general-purpose switching and amplification BC847/BC547 series 45 V, 100 mA NPN general-purpose transistors. Whenever base is high, then current starts flowing through base and emitter and after that only current will pass from collector to emitter http://www.edgefxkits.com/

Optimum Energy Management System Circuit Diagram Explanation: ďƒ˜ There are two pair sensors, each kept at certain distance from the other. One pair of sensor consists of a transmitter and a receiver, kept exactly opposite to each other. The transmitting part emits modulated IR light which is received at the receiver end and fed to a microcontroller of 8051 family. ďƒ˜ When a person enters the room then microcontroller senses it (with the help of IR sensors) and increments the count and displays it on 7 segment displays and also switches ON the load. In the same way when a person exits the room, the count gets decremented. When the last person exits from the room, the lamp is switched OFF. The load operation is handled by a relay interfaced to the microcontroller. http://www.edgefxkits.com/
Optimum Energy Management System Advantages: ďƒ˜ Managing and reducing energy consumption not only saves money but also helps in mitigating climate change and enhancing corporate reputation. ďƒ˜ Energy management is widely acknowledged as the best solution for direct and immediate reduction of energy consumption.
