Coin Drop Mobile Charger using IR sensor

Abstract

The coin based mobile charger developed during the process is providing a featured
provision to the public where power is not available for certain inconvenient time in mobiles
and it provides a difficult view in the real world. The coin based mobile charger can be easily
installed in any mobile phones. In rural area, mobile communication is essential when
compared to urban area while urban population use more sophisticated mobiles with
advanced technology such as more applications and good power backup for several days.
The rural population can buy the pre-owned mobiles that requiring charge frequently. Many
times battery becomes dead charge in the middle of any estimate particularlyin convenient
and need for ambient times when access to a standard charger is not possible nor available.
The coin-based mobile battery chargers are designed to solve this issue. The user has toinsert
the mobile phone into one of the universal chargers and insert a coin or two, the phone
willthen be given a micro-pulse for charging. It cannot produce full power to the mobile
phone which is required. The charging capacity of the mobile is designed with the helpof predefined values to provide the needed charge for emergency purpose. Of course by inserting
more coins the charging produced is more. This advantageous lightweight product is
designed and fixed to areas forthe growing number mobile users worldwide. A suitable
microcontroller(pic) isprogrammed for all the controlling applications. The source for
charging isobtained from direct power from battery and in case of non-availability of power.
