A Low-Cost Coin-Operated Cell Phone Power Charger

Deepak Raghav

Abstract


The "coin-operated cell phone charging" system primarily targets rural areas. People have a lot of trouble charging their mobile phones because electricity is a big problem in ruler areas. In the proposed system, they only need to put some money in the system to charge their cell phone. The proposed system uses 5 volts and is inexpensive. For coin identification IR based coin identifier (independent) is utilized. At the point when coin is putted in the openings it will recognize and PDA will begin charging for a fix time term. Using the Android app that was made just for it, the owner of the entire system can get the update.
