MINIMUM PULSE MONITORING SYSTEM ON PREPAID KWH METERS BASED ANDROID

Abstract

Electricity is an energy that is needed for human life in this modern era. Electricity serves to power all electronic equipment that we have. Prepaid electricity uses a pulse system, so we have to keep the pulses from running out so that the electricity doesn't go out which can potentially damage electronic items that are connected to electricity. Even though they have used a prepaid system, electricity customers are still unable to control their electricity usage. Moreover, due to technological developments so rapidly that almost everyone has an android smartphone, a tool is needed to convey minimum pulse warnings and daily power usage directly to electricity customers' android smartphones. This tool is designed to use the PZEM-004T sensor module to detect current, voltage, power and energy values ​​so that power usage can be known at a certain time. The data is processed on the ESP32 and then submitted to Nextion as an offline monitoring media, as well as telegram and blynk on the user's smartphone through the help of the internet as an online monitoring medium.
