The development of internet technology today is not only as a sender or transfer of data or files, internet technology can already be used to access physical objects such as hardware, for example sensors or motors and other electrical equipment. With this technology, it allows people to work remotely, for example controlling something or monitoring the data taken. Electrical energy measuring devices such as the kwh meter used by PLN record the calculation of the monthly electricity consumption from the house. Then an IoT-based remote monitoring device is needed to monitor electrical energy at home. The design of a remote electrical energy monitoring device at home uses components such as the ACS 712 sensor which functions to detect electric currents entering electrical components. ATmega 328 microcontroller which functions as a signal processing input from the sensor. And the output is LCD. LCD (Liquid Crystal Display) which functions as a display of values read by the sensor. MCU V3 which functions as displaying the value read by the sensor, then the data is sent to the cellphone using the internet network. The working principle of an electrical energy monitoring device. When an electric current flows into the power supply circuit. Then the ATmega 328 microcontroller processes data from the sensor. And the sensor detects incoming currents ranging from 0.45 A to 4.49 A. And the sensor detects output voltages ranging from 0.16 V to 2.25 V. If data from the sensor has been detected, the ATmega 328 microcontroller sends data to LCD and MCU V3 which functions as a display of data values from sensors. The program algorithm can be made in C language with the help of the Arduino IDE version 1.8.20 software. The program code is written in the editor then compiled and uploaded to the Arduino microcontroller. After completing the upload process, the program can be run on the Arduino microcontroller.
