Analysis and Monitoring Energy Consumption in Basic Electric Bills

The energy consumption of electrical household appliances is strongly influenced by the behavior of the people who live there. The ignorance of using the electrical appliances led to an increase in electricity bills every month. In order to achieve savings, a technology for monitoring electrical energy consumption is needed. This paper proposes a system designed for monitoring the power consumption of appliances in the home and sending the value to the Blynk application. This system uses an Esp32 board, a current sensor (SCT-013), a voltage sensor (ZMPT101B) and an LCD. The value detected by the sensor is sent to the LCD and Blynk to display current, voltage, power, and kWh. This allows users to monitor power consumption through the Blynk application on their smartphone and calculate power consumption on a daily or monthly basis.
