SOLAR AUTOMATIC MOBILE CHARGER WITH PAY SYSTEM
 ABSTRACT:

• Mobile phones’ becoming the major source of business/personal communication, the mobile phone business is currently worth billion of dollars, and supports millions of phones. The need to provide a public charging service is essential. Many critics argued that a public mobile phone charging service is not a lucrative business because most users can charge their phones at home, in their office or in their cars. Coin Operated Mobile Phone Charger is a new business milestone because many are attending business conventions and forgetting their charger at home or in hotel rooms. Students and many that use the public transportation that don't know that their level of their battery is low are prospective customers for coin operated mobile phone charger service. Recommended locations include: Hotels, conference centers, exhibition halls, serviced offices, exchange halls, motels, leisure centers, health clubs, training centers, golf clubs, retail outlets, shopping malls, Internet cafes, universities, colleges, hall of residence, airports, train terminals, etc., so that the mobile phone users can reactivate a low or dead battery by simply plugging in and charging for one rupee. Here is a design based on ATMEL 89c51 a 40-pin micro controller that does the countdown timing for a period of 3 mints with LCD displays showing the actual time left. During the timing period a relay output is latched and a flashing led indicates timing in progress.
INTRODUCTION:
• In this project it is proposed to capture the Sun's radiant light energy and convert it into electrical energy. Nature has been capturing the energy in light for millions of years. Each leaf is a form of solar cell, producing energy for plants and trees to grow in a chemical process known as Photosynthesis.
• A solar panel or battery converts the sun's energy to electricity. Gerald Pearson, Calvin Fuller and Daryl Chapin invented the first sun energy battery in 1954. The inventors created an array of several strips of silicon (each about the size of a razorblade), placed them in sunlight, captured the free electrons and turned them into electrical current. Bell Laboratories in New York announced the prototype manufacture of a new solar battery. Bell had funded the research. The first public service trial of the Bell Solar Battery began with a telephone carrier system (Americus, Georgia) on October 4, 1955.
SOLAR CELL:
• A solar cell (or a "photovoltaic" cell) is a device that converts photons from the sun (solar light) into electricity. In general, a solar cell that includes the capacity to capture both solar and nonsolar sources of light (such as photons from incandescent bulbs) is termed a photovoltaic cell. Fundamentally, the device needs to fulfill only two functions: photogeneration of charge carriers (electrons and holes) in a light-absorbing material, and separation of the charge carriers to a conductive contact that will transmit the electricity. This conversion is called the photovoltaic effect, and the field of research related to solar cells is known as photovoltaics.
• Solar cells have many applications. Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites or space probes , consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications. Recently solar cells are particularly used in assemblies of solar modules (photovoltaic arrays) connected to the electricity grid through an inverter, often in combination with a net metering arrangement.Solar cells are regarded as one of the key technologies towards a sustainable energy supply.
RESISTOR
• A resistor is a two-terminal electrical or electronic component that resists the flow of current, producing a voltage drop between its terminals in accordance with Ohm’s law.
• The electrical resistance is equal to the voltage drop across the resistor divided by the current that is flowing through the resistor. Resistors are used as part of electrical networks and electronic circuits.
Applications:
• In general, a resistor is used to create a known voltage-to-current ratio in an electric circuit. If the current in a circuit is known, then a resistor can be used to create a known potential difference proportional to that current. Conversely, if the potential difference between two points in a circuit is known, a resistor can be used to create a known current proportional to that difference.
• Current-limiting. By placing a resistor in series with another component, such as a light-emitting diode the current through that component is reduced to a known safe value.
• An attenuator is a network of two or more resistors (a voltage divider) used to reduce the voltage of a signal.
• All resistors dissipate heat This is the principle behind electric heaters
