Abstract

In general, the measurement of current in a circuit using amperemeter. However, current measurements with amperemeter weakness was not able to display the form of a measurable current signal. In this project created a tool that can measure the flow and display of the measured current signal into a PC-based Microcontroller ATmega 8535. This design uses Hall effect sensors UGN3503 as current sensors, Hall effect sensor UGN3503 can measure the magnetic field generated from the teraliri wire electric currents. Sensor output voltage is equal to the electric current flowing in the wire. The working principle of the flow measuring device based on PC (Personal Computer) is the current detection circuit that is the Hall effect sensor UGN3503 used to measure the current flowing in a circuit then the current magnitude is converted into digital quantities by using 10-bit ADC which is owned by the microcontroller ATMega8535. Scale digital output from ADC is sent to a PC via the serial port and the PC data is converted into a form of signal. The existence of such forms results measurable current signal can then be easier in view of current changes occur in the series and can instantly save the data flow changes into the computer.
