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

current of 220/0.5 = 440 A which is 22 times the full-load current. This high starting current may result in: (i) burning of armature due to excessive heating effect‚ (ii) damaging the commutator and brushes due to heavy sparking‚ (iii) excessive voltage drop in the line to which the motor is connected. The result is that the operation of other appliances connected to the line may be impaired and in particular cases‚ they may refuse to work. In order to avoid excessive current at starting‚ a variable

substations. The electricity that passes through these lines is generally high voltage electricity and hence there are multiple mechanisms by which the same can be done at different places for different purposes. The electrical wires that are visible up in the sky connected to different poles are one of the most common forms of power transmission. It connects different substations across locations to transfer the high voltage electric power. Aluminium alloy is what generally used as the power transfer

Overview of the project: Circuit description TEXAS INSTRUMENTS MSP430G2231 is the heart and brain of this circuit .the internal adc of the mcu with a resistor network voltage divider is used to measure the input voltage. Then 3 digest of comm anode 7 segment display is used to display final converted voltage. As you can see in the schematic the displays are multiplexed with each other. means we switch on one display and put the corresponding digit on this while other two displays are

results of others working on galvanic electricity. Ohm’s Law - Using the results of his experiments‚ Georg Ohm was able to define the basic relationship between voltage‚ current‚ and resistance. The equation I = V/R is known as "Ohm’s Law". It states that the amount of steady current through a material is directly proportional to the voltage across the material divided by the electrical resistance of the material. The ohm (R)‚ a unit of electrical resistance‚ is equal to that of a conductor in which
