This is project that I did out of curiosity. In this project a Voltage sensor (ZMPT101B) and Current sensor (ACS712) are used to measure the voltage and current which in turn provide the Power.

Presented here is a optical wattmeter circuit to calculate the power consumed with the help of pulsing LED light of the energy meter.

The energy crisis, brought by rise in fuel prices and increasing electricity demand due to commercialization, increasing population, and rise in number of building structures and houses, has brought ...
