The current phase in the industrial revolution, “Industry 4.0” has transformed the concept of automation and robotic precision. Increased automation follows complex sets of machines. And complex set of devices brings in complex energy usage patterns. The current systems measure the power consumed in a unit time but, do not comment on the input obtained at the machine end. The proposed solution gives an idea about measuring the AC input power fed to the machine and progressively calculating the amount of power consumed and lost during the machine execution cycle. The numerical data does not always give the user can opt to understand the parameters thus, real-time adjustable charts are used to justify the insights. Dynamic data processing is implemented to reduce the latency.

The Embedded System consists of an 8-bit MCU attached with AC Voltage and AC Current Sensors, a Wi-Fi transceiver, and an OLED display, and has a backend supported with Python, MySQL, PHP, and HTML-CSS.

Keywords: Embedded Systems, Energy Monitoring, Flask, RMS AC Power Measurement
