PROGRAMMABLE ELECTRICAL LOAD SURVEY POWER METER

The system is designed in order to calculate the energy consumption of a load in units and the cost incurred over the use in rupees in accordance to the number of hours that the load is to be used. The result is provided instantly allowing user to save time wasted in energy audits. An energy audit is a power consumption survey of the amount of units consumed by a particular device and the cost incurred over it to determine if the device is economical use in domestic or industrial sectors. Since electricity cost per unit has increased a lot these days, energy audits for devices have gained importance. Our project consists of an instant energy auditing system using 8051 microcontroller that is able to calculate the consumed units and cost incurred by device use over given time. The input data including energy tariff and the number of hours device is to be used is fed by user into the system. Based on this data the system instantly displays the cost and units consumed within no time.
