In this study, analysis has been conducted to make an efficient measuring device that precisely calibrates the electrical power which is further interfaced with a computer via microcontroller ATmega328P-PU and a Processing program. This focused study majorly explains conditioning of analog signals, conversion of analog to digital signal (ADC) and digital data processing. The microcontroller delivers high resolution and better sampling rate capabilities. It is capable of measuring the energy used by the DC Voltage power source device of 20 Volt, and has power of 2 to 400 W.
