E-Billing System using Smart Energy Meter for Domestic Application

Current billing system requires a lot of manpower to monitor energy consumption from home to home. This research work is mainly focused on self-metering and smart monitoring systems with the help of the IoT cloud. The proposed system is designed and implemented on the printed circuit board. The total energy consumption and tariff can be calculated with the help of voltage-current sensors and Arduino. SD card module is also included with Arduino to gather required consumption data and further analysis in .csv format. In addition, the Serial communication protocol is also included to send the calculated energy data and price to Wi-Fi Module ESP8266. This data will be monitored in real-time through the Adafruit IoT cloud platform, which uses MQTT protocol and can be easily programmed into ESP8266. LCD is used to display energy units and prices. Apart from that if energy usage reaches beyond the monthly threshold value, then system will automatically send a warning SMS through the IFTTT protocol which can easily interact with the cloud and actions can be taken by the user.
