Abstract - The paper explain Coin Based Mobile Charger
Using Solar Tracking System .As whole world is going towards the new phase of technology our needs becomes more sophisticated, on the other hand we need speed, quality, and effectiveness . But battery life of a smart phone will never match that of an old phones, so it is the high on everyone priorities which smart phone should buy? Sometimes battery becomes flat in the middle of conversation particularly at in convenient times when access to a standard charger isn't possible. It is true that many consumers carry around chargers with them or can find them in an Airport terminal or even a retailer, but this requires a consumer on the go to tether themselves to an outlet while waiting for the charge to fill. There are also charging cases and back-up battery products, but these too are mere band aids to the issue at hand. So to operate these mobile phones public charging is needed, and it should be useful to public. This system that is solar mobile charger gives the charging to mobile phone and solve this problem. This system is like coin based phones which was famous in beginning of 20th century. This System is designed based on ATMega16 a 40 pin micro controller that count down timing for a particular time period which was predefine with LCD display showing the processes. The relay and LDR output is latched and finishing timing in progress. Keywords: Battery, Solar tracking system, LDR, ATMega16.
1. INTRODUCTION In the present day scenario power has become the major need for human life. Energy is an important input in all the sectors of any countries economy. The day-to-day increasing population and decreasing conventional sources for power generation, provides a need to think on nonconventional energy resources. Here in this paper we are looking forward to conserve the solar energy that gone wasted. With the growing speed of technology advancement, smart phone have become the essential component of daily life. Smartphone is mobile phone which offers advance technologies with functionality similar as a personal computer. There are also very advanced features in smart phone such as internet, instant messenger and email etc. As whole world is going towards the new phase of technology our needs becomes more sophisticated, on the other hand we need speed, quality, and effectiveness . On the other hand these feature should be combined in a solution small enough to carry it in the pocket. But battery © 2017, IRJET

life of a smart phone will never match that of an old phones, so it is the high on everyone priorities which smart phone should buy? It is true that many consumers carry around chargers with them or can find them in an Airport terminal or even a retailer, but this require a consumer on the go to tether themselves to an outlet while waiting for the charge to fill. There are also charging cases and back-up battery products, but these too are mere band aids to the issue at hand. So to operate these mobile phones public charging is needed, and it should be useful to public. This system that is coin based solar mobile charger give the charging to mobile phone. Sometimes battery becomes flat in the middle of conversation particularly at in convenient times when access to a standard charger isn't possible. The coin-based solar mobile battery chargers are designed to solve this problem. This system is like coin based phones which was famous in beginning of 20th century. Initially when we inserted the coin into coin insertion slot, it will detect that coin with the help of sensor. Then we can connect our mobile to the charging plug and charging will start. Charging is depend on the coin.
2. BASIC ASSUMPTIONS The design of Coin base Solar Mobile Charger is based on fallowing assumption: The charging current is up to 4.3AH@6v DC Provision to charge maximum five types of mobiles Alternate power supply is available in this system.
3. FLOWCHART OF PROPOSED SYSTEM
Start the system by inserting the coin. Coin will be detected by using coin sensor(IR sensor). If the coin is detected then charging will start, otherwise the coin will be refund. Connect the charger to mobile. Add more coins for further charging.
