1.0 INTRODUCTION

This is the smart coin based mobile charging system that charges your mobile for particular amount of time on inserting a coin. The system is to be used by shop owners, public places like railway stations to provide mobile charging facility. So the system consists of a coin recognition module that recognizes valid coin is found it signals the microcontroller for further action. if a valid coin is found it signals the microcontroller and microcontroller then starts the mobile charging mechanism providing a 5v supply through a power supply through a power supply section to the mobile phone, now systems also needs to monitor the amount of charging to be provided .So the system can be used for smart mobile charging at public places. The objective of this project is inserting the coin using charge for your mobile phone in public places. This project is very useful to people who are all using mobile phone without charging condition in public places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. A sensor system is used to detect the presence of coin. It may be of different type (IR sensor, Using LDR etc…). The coin is inserted between the transmitted and received signal. When a signal came from sensor unit, the microcontroller activates the charger unit for a predefined time. After that it will reset to normal case. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger, we will use charger to charge for our mobile phone. The major action in this system is controlled by transmitter section; this section consists of IR transmitter and IR receiver. Here we need to generate IR frequency continuously. So that by using a small tiny microcontroller frequency is produced and is connected IR receiver continuously receives the signals from the transmitter. Whenever the light path in between IR transmitter and IR receiver cuts by an obstacle receiver signal gives low to high pulse. By to the IR led to generate IR light rays of 38 KHz frequency. Connecting the receiver output to the micro controller interrupt pin, it gives interrupt to the micro controller immediately the system gives the buzzer and sends the message to the display on LCD display to the micro controller.

1.1 BACKGROUND OF THE PROJECT

The mobile phone market is a vast industry, and has spread into rural areas as an essential means of communication. While the urban populations use more sophisticated mobiles with good power batteries lasting for several days, the rural populations buy the pre-owned mobile phones that require charging frequently. Many times battery becomes flat in the middle of conversation particularly at inconvenient times when access to a standard charger isn’t possible. The coin-based mobile battery chargers are designed to solve this problem. The user has to plug the mobile phone into one of the adapters and insert a coin; the phone will then be given a micro pulse for charging. It does not bring a mobile from ‘dead’ to fully charged state. The charging capacity of the mobile is designed with the help of pre-defined values. It is of course, possible to continue charging the mobile by inserting more coins. This compact and lightweight product is designed to cater for the growing number of rural mobile users worldwide. A suitable microcontroller is programmed for all the controlling applications. The source for charging is obtained from direct power grid.

1.2 OBJECTIVE OF THE PROJECT

The objective of this project is inserting the coin using charge for your mobile phone in public places.

1.3 PURPOSE OF THE PROJECT

The main purpose of mobile charger is to reduce the wastage of electrical power which often arises due to negligence of the user. Once the coin is inserted, the coin acceptor detects whether the coin is valid or not.For each unit of price, the power is available only for a limited period. The arduino can calculate the time based on the number of coins inserted.

1.4 BENEFITS OF THE PROJECT

Useful to public for using coin to charge for the mobile phone in any palace.
It can be used for different type of mobiles.
It is used for emergency charging purposes.
It can be installed railway stations, bus stops, villages and rural areas and public places.
It can be installed in office and colleges for pay charging facility.

1.5 ADVANTAGES OF THE PROJECT

Simple and hand efficient.
Less expensive.
Reduced man power.
Low power consumption.
Installation is easy.
It can be useful while travelling and when we don’t have charger with us during travel.
Simple to operate.

1.6 AREA OF APPLICATION

The project can be used in the following areas:-

Railway station:-This type of project is used in railway station for public palace.
Shop:-coin based project charger is install any shop and earn money.
Rural areas:-This project is installing in rural areas where the power grid is not available at any time.
Public Place such as Hotels, Conference centers, Exhibition halls, Serviced offices, Exchange halls, Hotels, Health clubs, Training centers, Golf clubs, Retail outlets, Shopping malls, Internet cafes, Universities, Colleges, Hall of residence, Airports, Train terminals, etc.:-This project is very useful to people who are using mobile phone without charging condition in public places.

1.7 SCOPE OF THE PROJECT

This project is very useful to people who are all using mobile phone without charging condition in public places. In this project, who are all using mobile phones in outside of home are office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. A sensor system is used to detect the presence of coin.
