Introduction

Home security system is a combination of following alarm systems
a.     Fire Alarm
b.     Rain Alarm
c.     Foot Step Intruder Alarm
d.     Water Level Indicator Alarm
e.     Light Alarm

The main concept to include all the different types of alarm is to secure the entire home from all types of calamities may be natural or man-made. The circuit could also be helpful to save the intruders like thief attack.



a.     The fire alarm is fitted in such place in home where there may be chance of getting fire such as kitchen, near electrical distribution system of house, gas system of house etc.
b.     The rain alarm is fitted on the roof of the house so that when a water falls on the roof of the house the circuit gets its conducting situation and the alarm would start its operation so that the people inside the house will get notified about the weather condition and they could take preventive measure for their house.
c.     The water level indicator alarm is fitted inside the water tank, so that when water attains its maximum level, the alarm would get activated and the water pump should be switched off to save the wastage of the water.
d.     Most of the time people have to stand in front of the door and continuously ring the bell to open the door. But in modern scenario we will use foot step alarm which would make sound continuously till when the person doesn’t move from its place. This alarm could also be used in the window to protect the house from thieves.

Aim


The main concept of the project is to construct a simple but effective security system for home which consist of:-
a. Fire Alarm
b. Rain Alarm
c. Foot Step Intruder Alarm
d. Water Level Indicator Alarm
e. Light Alarm

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.

BLDC Motor Driven Solar PV Array with Battery Fed Automatic Irrigation System Employing Zeta Converter

Objective The main objective behind this project is to design a simple, cost effective and efficient brushless DC (BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system. The project includes automatic changeover circuit to switch power source between solar panel and battery based on the presence and absence of light. The pump works on the signals received by the sensors used for automatic irrigation system. Abstract This project proposes a simple, cost effective and efficient brushless DC (BLDC) motor drive for solar photovoltaic (SPV) array fed water pumping system. A zeta converter is utilized in order to extract the maximum available power from the SPV array. The proposed control algorithm eliminates phase current sensors and adapts a fundamental frequency switching of the voltage source inverter (VSI), thus avoiding the power losses due to high frequency switching. No additional control or circuitry is used for speed control of the BLDC motor. The

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 u
