Abstract

With the increasing the new tariff for electricity nowadays, people try to find a method to minimize their electricity consumption. But, this can only be achieved if they understand the pattern of their electricity consumption. A new device that can help user in gaining understanding about electricity consumption need to be developed. Therefore, this project has been conducted in order to increase the awareness of electricity usage among the residential consumers. This project consist of microcontroller, current sensor, LCD panel and switches. The current sensor will be clamped at the live cable in the main distribution board to sense the current flow. Then, the target value will be compared with actual usage of electricity. If the actual usage is exceeding the target value, a notification LED will turn on. The advanced power meter was designed with the ability to read the overall power usage in a house or at individual appliance and display the electric bill. This meter is suitable for the residential buildings as the current sensor used can measure RMS current up to 100A and power up to 240 kW. From the experiment conducted, the average highest error is 9.05% and the lowest average error made is 3.72%. Both error is less then 10%. Thus, the design power meter is reliable and robust to use.
