Economics and Environment Assessment of Smart Energy Electricity Meter for Residency Monitoring

Abstract

The energy meter is a device to measure energy utilities and is crucial to determine the daily energy usage. However, the current energy meter can only record the amount of power consumed but is still lacking in the monitoring system for power consumption. This paper implemented the concept of an IoT based energy meter using a simple low-cost NodeMCU microcontroller, an esp8266 Wi-Fi chip module and Blynk application. This device was constructed with an LED to represents the power consumption from the LED blinking with the base value set at 1000 pulse for 30 minutes, proportional to the energy meter time. This IoT based device will count the pulse from LED blinking and store the energy reading to identify the Maximum Demand (MD) in a residence based on the time and date of the reading taken. We set a certain limit for the power consumption and once the limit is reached, this IoT based device will send the notification through a Blynk application to enable users to control their energy consumption. This proposed design is beneficial in preventing any MD penalty to the users due to an excessive energy usage.
