  1. Prepaid Energy Meter with GSM Interface

  2. Prepaid Energy Meter with GSM Interface Introduction • The project has been introduced in the power sector to effectively record the units consumed for billing purposes and also monitor several other factors to reduce power theft and minimize losses that occurs due to conventional electromechanical energy meters. This is a multipurpose project that integrates all the functions including a prepaid billing arrangement and automatic message sending system to the utility company. http://www.edgefxkits.com/

  4. Prepaid Energy Meter with GSM Interface Hardware Requirements • Microcontroller (AT89C52/S52) • Max232 • GSM module • LCD(16x2) • LED • Crystal Oscillator • Resistors • Capacitors • Diodes http://www.edgefxkits.com/

  5. Prepaid Energy Meter with GSM Interface Hardware Requirements • Transformer • Regulator • Opto Isolator • Energy Meter • Lamp • push buttons. http://www.edgefxkits.com/

  6. Prepaid Energy Meter with GSM Interface Software Requirements • Keil compiler • Languages: Embedded C or Assembly http://www.edgefxkits.com/

  7. Prepaid Energy Meter with GSM Interface Power Supply • A power supply is an electronic device that supplies electric energy to an electrical load. Bridge rectifier 5v Regulator 230 V AC 50 Hz 5V DC Filter(470µf) 12V step down transformer http://www.edgefxkits.com/

  8. Prepaid Energy Meter with GSM Interface Power Supply • The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. http://www.edgefxkits.com/

  9. Prepaid Energy Meter with GSM Interface Power Supply • A DC Power Supply Unit (commonly called a PSU) deriving power from the AC mains (line) supply performs a number of tasks: • It changes (in most cases reduces) the level of supply to a value suitable for driving the load circuit. • It produces a DC supply from the mains (or line) supply AC sine wave. • It prevents any AC from appearing at the supply output. http://www.edgefxkits.com/

  10. Prepaid Energy Meter with GSM Interface Parts of a Power Supply • The output voltage is kept at a constant level, independent of changes in: • The AC supply voltage at the supply input. • The Load current drawn from the supply output. • Temperature. http://www.edgefxkits.com/

  11. Prepaid Energy Meter with GSM Interface Energy Meter • An energy or electric meter is a device that measures the amount of electrical • Energy consumed by a residence, business, or an electrically-powered device. • Electric meters are typically calibrated in billing units, the most common one being the kilowatt hour. • Periodic readings of electric meters establish billing cycles • and energy used during a cycle. http://www.edgefxkits.com/
