Comparative study of magnetic fields measurements with logger lite and Arduino on electronic devices

Abstract

A study of magnetic field measurements of electronics devices has been conducted. Magnetic field measurement is done by two methods, that is Arduino based measurement by using magnetic field sensor with C + language. Other measurements use magnetic sensors and Logger Lite software with Labquest Mini interface. In Arduino measurements, the measurement results are made in units of Tesla. ADC Arduino has 10 bits. The resolution of this magnetic sensor is 1.6 gauss/volt. Display data in the form of sensor read voltage is changed in milli Tesla (mT) by dividing the data reading voltage sensor value with a value of slop 0.160 mT and intercept -0.32 mT. Measurement results are compared with measurements using magnetic field sensors and free Logger Lite software. The results found that there was no significant difference on measurement data between Arduino and logger lite. The larger difference is 0.032, a result of Servo measurement and the lower is 0.002 mT, result of Coil with 1 Ampere measurement. The conclusion of these two methods is the measurement of the magnetic field using Arduino is recommended to be used.
