CHAPTER 1 INTRODUCTION This project “DTMF REMOTE APPLIANCE CONTROL SYSTEM USING MOBILE PHONE” is used to control appliances which are far away from the user using mobile phone. The aim of the proposed system is to develop a cost effective solution that will provide controlling of home appliances remotely and enable home security against intrusion in the absence of homeowner. The devices connected as home and office appliances consume electrical power and they should be controlled as well as

Remote Control For Home Appliances This is a simple remote control circuit based on infrared sensor IC TSOP1738. TSOP1738 contains photo detector and pre-amplifier both in one package. It is a three terminal device. Pin 1 is for ground‚ Pin 2 is for power supply and pin 3 is used as output. Pin diagram of TSOP1738 is shown below. Take care while connecting the pins of TSOP1738. Wrong lead connection of TSOP1738 may lead to sensor damage. CD4017 is a CMOS counter/ divider IC. It takes clock signal

REMOTE CONTROLLING OF HOME APPLIANCES ABSTRACT The main aim of conducting this project is to control a maximum of eight electrical appliances by just using a TV remote. Normal IR circuits can switch only one device. But using this circuit‚ different devices can be controlled using same remote with different switches. In this circuit‚ we interfaced 8 devices. These devices are switched using remote keypad -1 to 8. AT89C51 microcontroller is used to control the inputs and

other types of power supplies7805 IC has a thermal shutdown feature to protect the IC in case of overheating so it should be safe to use 7805 without a heatsink plate for less than 200mA load. However should your load cross 200mA‚ you should consider using a heatsink plate. Heatsink plate should be large enough to bring 7805 heat to such a level that you can comfortably touch it The two capacitors used in the voltage regulator circuit are not mandatory but they are good to maximize voltage

of interest to control systems of his/her choice. In the age of electronic systems it is important to control and acquire information from everywhere. Although many methods to remotely control systems have been devised‚ the methods have the problems. Hence the need for special devices and software came to control the system. This suggests a method for control using the DTMF tone generated when the user pushes mobile phone keypad buttons or when connected to a remote mobile system. In

aUTOMATED DEVICE CONTROL USING DTMF. ABSTRACT Now a day’s every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations‚ so that the flexibility‚ reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance. Probably the most useful thing

inventions have been produced to facilitate our living. One of them was the mobile phone. When the first one was launched in 1973 by a company called Motorola‚ a new lifestyle with many new attributes has been established. What are the benefits that it has brought to us? In my opinion‚ there are three advantages that it has: communication‚ entertainment‚ and providing benefits. The first important one is global communication. Cell phone allows us to communicate with our family and friends no matter where

Construction of Gate Remote Control A remote control is a component of an electronics device‚ most commonly a TV‚ Car door‚ and Gate originally used for operating the device wirelessly from a short distance. Remote control has continually evolved and advanced over recent years to include Bluetooth connectivity‚ motion sensor enabled capabilities‚ internet and voice control. Commonly‚ remote controls are Consumer IR devices used to issue commands from a distance to televisions or other consumer
