Abstract :
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.
