A Light emitting diodes (LEDs) have gained broad recognition as the ubiquitous little lights that tell us that our monitors are on, the phone is off the hook or the oven is hot semiconductor.

The basic principle behind the emission of light is that: When charge carrier pairs recombine in a semiconductor with an appropriate energy band-gap generates light. In a forward biased diode, little recombination occurs in the depletion layer. Most occurs in a few microns of either P- region or N ?region, depending on which one is lightly doped.

STREET LIGHTING SYSTEM



In India you must have seen many places where Street Lights will be ON whether its day time or night or worst is the case when it will be ON for 24 hours. This wastes lots off electricity and to save energy is one of the most important tasks nowadays where our resources are being finished.

This project consists of an RTC which is responsible for generating time. We will write the program such that depending on the time the light will be ON or OFF.

In place of RTC we can use LDR which will see the brightness ....etc

Authentication plays a very critical role in security-related applications like e-commerce. There are a number of methods and techniques for accomplishing this key process. In this regard, biometrics is gaining increasing attention these days. Security systems, having realized the value of biometrics, use biometrics for two basic purposes: to verify or identify users. There is a number of biometrics and different applications need different biometrics. Biometric is the most secure and convenient authentication tool. It can not be borrowed, stol ....etc

control of Home Lighting System
has developed from standalone type to more complicated networking controls. Many building management system and even the security system have incorporate the control of lighting into their system as a total solution to their customers. However, there are still no single universal protocol for the building or lighting control system.

The lighting industry has developed a new standard for communication with electronic ballast. Electronic ballast is a common lighting device that is used in practically every buil ....etc

Abstract ” In other to save energy, several countries recently made laws related to standby power consumption. To success this exertion, we should consider not only power reduction of consumer electronics itself but also efficient automatic control in networked home environment. In this paper, we present a design approach and implementation result of control mechanism for standby power reduction. Proposed mechanism has the Host-Agent based structure and uses the IEEE 802.15.4 based ZigBee protocol for communication and security between H ....etc
