SMART HOME AUTOMATION USING DTMF

1. INTRODUCTION

We use many different types of communication in control applications to control home appliances, industrial appliances, and other type of automation. There are two types of communication that is we generally use - one is wired and other one is wireless. In wireless communication we transmit signal wirelessly, like using radio frequency (RF) and in wired communication in which we use wires like copper wire. In this project “DTMF Based Home Automation System” we are going to control our home appliances wirelessly. Other important feature of this project is, that we are not going to use any microcontroller in it.
.
The remote control used in home automation systems, is a wonderful feature that everyone would like to enjoy, if they were not expensive to install, maintain, and able to be use from long distance. With such automation one can switch ON and OFF lights, Ac etc. from a remote distance. In our project we have tried to implement this home automation technique using DTMF.

Full Wave Bridge Rectifier With Capacitor Filter

 Full Wave Bridge Rectifier With Capacitor Filter The voltage obtained across the load resistor of the full-wave bridge rectifier described above has a large amount of ripple. A capacitor filter may be added to smooth-en the ripple in the output, as shown below. Figure 21: Full wave Bridge rectifier with capacitor filter The rectifier circuits discussed above can be used to charge batteries and to convert AC voltages into constant DC voltages. Full-wave and bridge rectifier are more commonly used than half-wave rectifier.

MATLAB

Introduction to MATLAB Goal The goal of this tutorial is to give a brief introduction to the mathematical software MATLAB. After completing the worksheet you should know how to start MATLAB, how to use the elementary functions in MATLAB and how to use MATLAB to plot functions. What is MATLAB? MATLAB is widely used in all areas of applied mathematics, in education and research at universities, and in the industry. MATLAB stands for MATrix LABoratory and the software is built up around vectors and matrices. This makes the software particularly useful for linear algebra but MATLAB is also a great tool for solving algebraic and differential equations and for numerical integration. MATLAB has powerful graphic tools and can produce nice pictures in both 2D and 3D. It is also a programming language, and is one of the easiest programming languages for writing mathematical programs. MATLAB also has some tool boxes useful for signal processing, image processing, optimization, etc. How ...
