Low Cost Coin-Operated Cell Phone Power Charger

Priti Kumari, Ruby Yadav, Deepak Kourav

Abstract


“Coin operated cell phone charging” system is basically intended for rural areas. Because in ruler areas electricity is big problem, people face many problems in cell phone charging. In Proposed system they can just put some coin in system and they can charge their cell phone accordingly. Proposed system is low cost system that works on 5 volts. For coin detection IR based coin detector (self-made) is used. When coin is putted in the slots it will detect and cell phone will start charging for a fix time duration. Owner of the whole system can get update using the android app specially designed for it.

 

Key word: Coin detector, IR sensor, android application
