Electrical Consumption Monitoring and Controlling System Based on IoT and Mobile Application

Abstract

In addition to the increase in basic electricity Tariff or Tarif Dasar Listrik (TDL), the high cost of electricity consumption is also influenced by our lack of awareness or lack of care in our daily use of electronic devices. This study aims to design and create a prototype that can monitor and control the use of IoT-based electronic devices or via the internet where electricity consumption data is stored in the Firebase real-time database using the ACS712 current sensor, ZMPT101B voltage sensor, an Arduino microcontroller, and NodeMCU V3. This tool will send current, voltage, and wattage data into the database, and then it will be converted into kWh. Also, the costs arising from electricity consumption based on the PLN electricity base rate, and the results can be seen directly through an Android phone. This system can monitor electricity consumption for four electronic devices. Also, to monitor this system, it can control electronic devices using a relay module, which functions as an electric switch to turn on and off electronic devices controlled via an Android device. This system can monitor electricity usage for three units of electronic equipment, i.e., water pump (unit 1), 14" CRT TV (unit 2), and Dispenser (unit 3). It's also succeeded in reducing electricity consumption. In unit 2, the decline occurred as much as 27.49%, And In unit 3, the fall occurred as much as 57.28%. From the overall test results, the system can be categorized as working well so that it is feasible to be implemented in the household for savings in the use of electricity
