Analisa Dan Rancang Bangun Alat Ukur Arus, Cosphi Dan Tegangan Listrik Digital Dengan Tampilan Personal Computer (Pc)

This system is designed using Arduino Uno, acs712 current sensor and voltage sensor zmpt101b. The purpose of this research is that residential users can use this tool to determine the overall electrical power used for the house so that there is no electric power overload that causes the main circuit bracker (MCB ) at kwh meter loss or down and for technicians can see the results of measurement of electrical power that is in the factory or PLN more thoroughly. Then the sensor readings in the form of graphs and tables will be visible to the PC connected via the ethernet shield board. The maximum voltage that can be read by the zmpt101b sensor is 226,37 volts, and the maximum current that can be read by the acs712 sensor is 4,43 ampere. The measurement results are taken from the average value of sensor readings
