Traditional energy meter needs to be observed manually for billing monthly. In replace of the traditional system, a prepaid meter is introduced to measure the power consumption and bill is prepaid through dialing a series of digits into the meter Dialpad. To know the amount of consumed power, consumer needs to check the meter physically by dialing a short length code. This research paper proposes a real-time GSM based smart energy meter, providing accurate measurement of power and cost calculation, better utilization of labor, portable and cost-effective. A Microcontroller is used to measure the voltage, current, energy and unit cost and a GSM module for notifying the consumers and distributors about usage alongside with monthly billing through SMS service. To show the real-time voltage, current, energy with an invoice for consumer notation a 16×2 LCD has deployed. An immaculate multimeter, perfectly aligned with this wattmeter, is used to measure the line voltage and current. To calibrate the proposed wattmeter a variable rheostat has utilized where its value is non-linear compared with a traditional wattmeter and found that the accuracy is nearly 98%. Moreover, Prediction of the next day usage of power makes the proposed system more unique. In consequence, it will help the consumer to be economical in power consumption and the rate of daily power wastage will be reduced drastically. The designed system is accurate in the billing process, notify and predict the usage, easy to install and adds an extra dimension in consumer satisfaction level. |
