‘HILIR’ MOBILE APPLICATION DEVELOPMENT FOR MONITORING AND CONTROLLING ELECTRICITY USAGE BY UTILIZING PZEM-004T SENSOR AND NODEMCU ESP8266 AS MICROCONTROLLER USING FLUTTER

Abstract

Technology is developing rapidly. Along with the development of this technology, people's activities in this millennial era are getting busier, so that in the midst of these activities, people often forget that the availability of electrical energy is very limited and the cost for electricity is also increasing, so that people's efforts to monitor electricity use in their homes are limited. The problem is how to develop a mobile application that can be used to monitoring electricity usage in real-time and control the electronic device on/off remotely. The writers gain references from analysing a similar application that already exist as the method. From analysing the business process of the projects shows that, this application has utilized an IoT device to support the real-time monitoring and control. Real-time monitoring is a feature that

the writers develop to help user see the electricity usage of an electric device on real- time through menu on the home screen of the application. Through this real-time

monitoring features, the user can determine what devices that should be turned on or off to save more on electricity usage cost.
