to investigate the places where electrical energy is consumed. The effective energy usage of a device can often be determined by monitoring the according electrical devices over a long space of time. The measuring can easily be done by simple Energy Meters from the local do-it-yourself store. An energy meter is a device that measures the amount of electrical energy that is being consumed by a residence‚ business‚ or an electrically powered device. Electric meters are typically calibrated in billing

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
