Application of Water and Wind Energy for Low Cost Portable Mobile Phone Charger (PMPC)

摘要

The primary focused of this project is to develop a portable and low-cost electric generator purposely as a mobile phone charger by using two renewable energy sources that are wind and water. Usually, when people went into the forest for camping, they will get hard to charge their phones. They can use a power bank to charge up their phone but not for so long because the power bank also will be empty sooner or later. They need a very convenient way to charge their phones or power bank. There is also solar charger power bank but this kind of Portable Mobile Phone Charger only use the sun as the source which can cause problems when it comes at night time. The user had to wait for sunrise to charge the power bank. Sometimes, the consistency of using the solar power bank also drops when in the forest. There are limited sunlight. Hence, the user needs an unlimited energy source that they can use to generate electricity. This project uses renewable energy as the main source of this project. The two energy is wind and water. These energies will be used to harvest electrical energy to charge mobile phones and other small electronic applications. When the energy is in contact with the turbines, it will produce electricity. A small DC motor and the hydro generator will be used. After generating the electricity, it will be stored in the capacitors. These capacitors act as energy storage to charge the mobile phone. Next, Arduino Uno is used to read the voltage output from the wind generator and the water generator and display the voltage reading using the LCD display. The LCD will display the changes in voltage from the wind and water generator. This will alert the user about how much the output voltage obtains from the motor generators. Then, the voltage will be step up and maintain to 5 volts because that is the main target for this project that is to produce a 5 volt as the output to charge mobile phones. The LCD display will display few readings of the voltage in three diffe
