Abstract :
Current advances in digital tecnology are veryinfluential on the use of measuring
instruments. This thing we can see many found various kinds of measuring devices using
digital tecnhology. With the advancement of digital tecnhology, research in the field of
electrical power and electronics can be done better and faster. Besides using digital
technoloy, measuring instrumenst are made in a simple form and can be carried
anywhere.
This study discusses how to make an electric power measuring instruments in the
form of calculating current and voltage, this tool is designed and analyzed a
microcontroller-based electrical power measuring device using current sensors and
voltage sensors, and the power-use display will be seen on LCD.
This tool uses current sensors and voltage sensors, for the accuracy of the
measurement data that is read by the sensor when comparad to the data instrument has an
accuracy level avove 90%. The greater the power obtained. Calculation and processing of
a data used by value of the value used by Arduino Uno and displayed on the LCD.
