The Prototype of Smart Power Meter at Home Based on Internet of Things

Information and communication technology is developing rapidly, one of which is the development of technology in the field of the Internet of Things that is able to connect several devices wirelessly through the internet network. The electrical energy consumption monitoring tool that has been made in this study uses the PZEM-004T module. This system is designed and utilized to read the amount of electrical energy consumption which includes voltage, current, active power and energy accumulation. The monitoring system is connected to an android smartphone which is used as a media user interface that displays web-based electrical energy consumption. The test results show that the monitoring tool for electrical energy consumption using the PZEM-004T module can measure and display the values of current, voltage, active power and energy accumulation in real time and stored in the database. Based on the test results, it can be concluded that the design results of the electrical energy monitoring tool have a deviation or error value (%) on the PZEM004T sensor compared to the power meter at a voltage of 0.616 %, for a current of 21.027 %, a power of 3% and a frequency of 0%.
