Dear Sir,
I was looking for coin based mobile charger water filling and weight measurement system project for my EEE final Sem project.It will be of great help if you can kindly provide me with the same and guide me...
Thank You

The mobile recharge system based on smart coins that charges your mobile for a certain amount of time when inserting a coin. The system should be used by store owners, public places such as railway stations to provide mobile charging facilities. Therefore, the system consists of a coin recognition module that recognizes valid currencies and then signals the microcontroller for further action. If a valid coin is found it points out the microcontroller and the microcontroller then initiates the mobile charging mechanism by providing a 5V supply through a power supply section to the mobile phone, now the system also needs to monitor the amount of charge to be provided . Thus, the microcontroller starts a countdown timer to display the charging time of that mobile phone. Now, if the user inserts another coin at that time, the microcontroller adds the time to the current load time and starts the countdown. So the system can be used for intelligent mobile charging in public places.
The mobile coin-based battery charger developed in this document is providing a unique rural public service where network power is not available for the partial / full day and a source of revenue for site providers. The coin-based mobile battery charger can be installed quickly and easily outside of any commercial establishment. The mobile phone market is a large industry and has spread to rural areas as an essential means of communication. While the urban population uses more sophisticated mobiles with good power batteries that last several days, the rural population buys the pre-owned cell phones that require frequent charging. Many times the battery becomes flat in the middle of the conversation, especially at uncomfortable times when access to a standard charger is not possible. Coin-based mobile battery chargers are designed to solve this problem. The user has to connect the mobile phone in one of the adapters and insert a coin; The phone will receive a micro-pulse to charge. It does not bring a 'dead' phone to a fully charged state. The carrying capacity of the mobile phone is designed with the help of predefined values. Of course, it is possible to continue charging the mobile by inserting more coins. This compact, lightweight product is designed to serve the growing number of rural mobile users around the world. A suitable microcontroller is programmed for all control applications. The source of charge is obtained from the direct electricity grid and from solar energy in case of non-availability of the electricity grid.
