This Project Report On Coin Based Mobile Charger is very useful to people who are all using mobile phone without charging condition in public places. This project is very useful for people who use any phone without charge in public places. In this project, all of which are equipped with mobile phones outside your home office for free. The coin-based cell phone charger is very useful for that person to use a coin for the mobile charge carriers. Infrared sensor is an electronic device that measures infrared (IR) light radiating from objects in its field of view. Apparent motion is detected when an infrared source with one temperature, such as human, passes in front of an infrared source with another temperature, such as a wall.

The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile. The IR (infrared) transmitter is used to transmit IR signal in the transmitter side. The IR receiver is used to receive the IR signal in the receiver side. Between the IR transmitter and receiver, insert a coin to change the polarity of pulse in SCU input. The SCU is used to converting low pulse to high pulse and that pulse is inverted in inverter. The 555 IC is act as a timer to produces high pulse for particular time period. Again the SCU is used to converting low pulse to high pulse and this output is give to input of driver circuit. Driver circuit is used for provide the sufficient input voltage of relay. The relay will on to activate the 230v charger.


The main merits of the coin-based cell phone charger, Simple and hand efficient. No expensive. No power consumption.

Project Report On Coin Based Mobile Charger Conclusion:

This project is useful for; who are all using mobile phones in outside of home or office without charging condition. The coin based mobile phone charger is very useful to that person for using coin to charge for that mobile.
