A setup facilitating such a thing would be to connect the home appliances to a microcontroller interfaced to a GSM modem that receives the controls from the user‚ the means of sending signals to the appliances being a mobile phone. This project is an implementation to the idea of the wireless communication between a mobile phone and a microcontroller. Our administrator uses a simple GSM based handset for sending messages to different display stations which are

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

sophistication of the house by monitoring and controlling the devices using RF and VOICE technologies. The main motto of the project is to ensure complete safety and automate all the devices. This is done by interfacing all the devices to a PIC microcontroller”PIC16F84A”. Apart from alerting the user regarding threats a feature is provided where the user can monitor and control all the devices such as tube lights‚ fans‚ air conditioners‚ refrigerators etc. whenever there is a power cut the user is immediately

Automatic disconnection of the meter takes place on expiry of credit. The device is based on 8051 microcontroller. It uses IC-AT89S52 of 8051 family. The project is being made with the intention of getting into the practical application. Overview of Method: Prepaid meter is essentially an energy recorder cum controller.

The GPS will monitor speed of a vehicle and compare with the previous speed in every second through a Microcontroller Unit. Whenever the speed will be below the specified speed‚ it will assume that an accident has occurred. The system will then send the accident location acquired from the GPS along with the time and the speed by utilizing the GSM network. This

Proposed automated project involves measuring the power factor value from the load using microcontroller. The design of this auto-adjustable power factor correction is to ensure the entire power system always preserving unity power factor. The software and hardware required to implement the suggested automatic power factor correction scheme are explained

Once the arrival of the train is sensed‚ the sensed signal is sent to the microcontroller via‚ wired or wireless transmission and it checks for possible presence of vehicle between the gates. Subsequently‚ buzzer indication and light signals on either side are provided to the road users indicating the closure of gates. Once‚ no vehicle

CHAPTER 1 INTRODUCTION 1.1 ABOUT THE PROJECT Independent mobility of visual impaired is difficult. Generally‚ to explore the space‚ sightless people use other senses (i.e. hearing‚ touch and smell) to compensate their disability. In familiar settings they learn how to orientate in the spaces by recognizing known features (points of reference). Nevertheless In unknown environments‚ navigation often becomes harder or even dangerous. Besides‚ in pre-designed environments
