Residential Safety System with Gas and Fire Detection and Auto Intimation to User Mobile
An embedded system for the purpose of a residential Safety System with Gas and fire detection and auto Intimation to user mobile is developed in this project.The fire accident and the gas leakages are detected using two different sensors which are installed in the building. A GSM modem is used for the purpose of automatic intimation to the user's mobile number.The sensors are interfaced with the microcontroller through an ADC and it is responsible ....etc

ABSTRACT

The objective of this project is to design electronic energy meter. Presently With the help of electromagnetic energy meter the amount of the electricity usage can be calculated. This project helps to design electronic energy meter. To identify the amount of the power used by the house can be calculated using I sense and V sense. V sense contains the Potential transformer rectifier unit and the Zener diode. Zener diode is used for the function of maintain the voltage level up to 5V. I sense contains the current transformer re ....etc

New Technology for Preventing Residential Electrical Fires: Arc-Fault Circuit Interrupters (AFCIs)




INTRODUCTION

Annually, over 40,000 fires are attributed to home electrical distribution systems.
These fires result in more than 300 deaths and over 1,400 injuries each year. Statistics
from 1992-1996 show level trends in each of these estimates with no indications of
decline. In 1996, $680 million in property loss was attributed to home electrical
distr ....etc

Residential Piezoelectric Energy Sources




Technical Overview
Piezoelectric materials exhibit the unique property known as the piezoelectric effect. When these materials are subjected to a compressive or tensile stress, an electric field is generated across the material, creating a voltage gradient and a subsequent current flow. This effect stems from the asymmetric nature of their unit cell when a stress is applied. As seen in Figure 1, the unit cell contains a s ....etc

AN OVERVIEW OF HUMAN TENDANCY
SINCE THE ORIGIN & MAN KIND ON THIS EARTH MAN IS HUNTING FOR HIS DEFACE AGAINST VARIOUS NATURAL CALAMITES.
AFTER FOOD & CLOTHES A PLACE FOR SHELTER IS THE MOST ESSENTIAL THING FOR HUMAN BEING.
FROM ANCIENT TIMES TILL NOW HE IS STILL OF SAME NATURE,THE SAME ELEMENTARY NEEDS BUT THE DIFFERENT DESIRES FORCES HIM TO MODIFY HIS LIVING STYLE.

Abstract
This study investigated recent changes in migration and population structure of the Greater
Bangkok considering the impact of economic globalization. The spatial policy of the Thai
government has lead newer investments for manufacturing to locate away from Bangkok
Metropolis and thereby the industrial structure of Bangkok Metropolis has gradually turned
into service-dominated, while the region surrounding Bangkok Metropolis has attracted
factories mainly owned by foreign capital. Light industry and electr ....etc

Abstract

The DELTA Smart House is going to have a large number of sensors and microelectronic devices located throughout the house. These devices will need a clean, reliable source of energy that wonâ„¢t need constant maintenance. The goal of this seminar is to discuss utilization of piezoelectric energy sources to provide power to certain applications in the house. Initially an energy scavenging floor that used piezoelectric transducers to harvest wasted energy in the foot strike of a human being. In consideration of the high cos ....etc
