Abstract

Currently, the new tariffs of Tenaga Nasional Berhad (TNB) is been introduced to the users. For the domestic, there are five types of tariffs range of electricity usage. For example, the first range is from 0 kWh until 200kWh, where the user is been charged for RM21.80. If the users used only 150kWh only, they also need to pay the bill for RM21.80. This is disadvantages for the user because they do not know the accurate bill until they received the electricity bill the end of the month. If the users know total amount the usage of electricity, they can control the usage and the bill as well. Thus, the electric profiler system using Arduino is being built for the user to monitor the current usage of electricity at their household. This electric profiler system device is an alternative path to prevent the users to pay the electricity bill more. This project helps the user to save cost and the usage of electricity. There are cases where the officers of Tenaga Nasional Berhad (TNB) check the current meter by assuming the meter from far. Then, the actual electricity usage is not been calculated correctly. It is harm to the users whose they need to pay more from the actual bill due the officers assume the usage is higher from the last month. If not, the Tenaga Nasional Berhad (TNB) will be loss and because of that, the users need to pay the consequences. This is how the electric profiler system device is being an idea to the project. This system was divided into two parts, which are the hardware design and software implementation. The hardware design involved the Arduino UNO, real time clock, LCD display with I2C serial and ACS712 current sensor. For the software implementation, the coding for the hardware component is being installed in the Arduino UNO. The message of “Electric Profiler” is appeared on the screen then the “Welcome” is displayed after. Then, when the switch is being on, the ACS712 current sensor detected the current and sent the data to the Arduino UNO. Thus, the Arduino converted the data into the bill for the user that display on the LCD display. The total of electric usage also been display on the screen before the bill is appeare.
