Talking Energy Meter The purpose of this project is to build a KWH (Kilo Watt Hour) meter that can alert the users with voice messages. An Energy meter or KWH meter is a device that measures the amount of electrical energy supplied to or produced by a residence‚ business or machine. Electricity is a clean‚ convenient way to deliver energy. The electricity meter is how electricity providers measure billable services. The most common type of meter measures kilowatt-hours. When used in electricity

I2C IMPLEMENTATION USING ARM FOR WIRELESS COMMUNICATION Automatic meter reading is the technology of automatically collecting consumption‚ diagnostic‚ and status data from water meter or energy metering devices (gas‚ electric) and transferring that data to a central database for billing‚ troubleshooting‚ and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time

INTRODUCTION The automatic meter reading(AMR) system as become a necessity for most suppliers as deregulation‚ free customer choice and open market competition occur in the energy supply sector. Power line communication has many new service possibilities on the data transferring via power lines without use extra cables. AMR is a very important application in these possibilities due to every user connected each other via modems using power lines. AMR is a technique to facilitate remote readings energy consumption

1. INTRODUCTION The project “Automated Electricity Meter” aims to move away from the traditional method of manual reading of electricity meters in which an individual has to physically record the reading. Instead the project proposes to successfully be able to take the meter reading automatically without having a person be physically present while taking the reading‚ thereby reducing manpower requirement. This system helps the users by alerting them about the peak loads (max energy consumption)

A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances). A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. The probe The pH probe measures pH as the activity of hydrogen ions surrounding a thin-walled glass bulb at its tip. The probe produces a small voltage (about 0
