3-Axis Magnetometer Build
170421 Like and subscribe. This is an archive, check the link in the end if you are. This video shows how to create a magnetometer using hall effect sensors. It uses (3) A1309 sensors to read up to +/- 220 Gauss on 3 axes, and (1) A1308 sensor to read up to 1500 Gauss. One Gauss is 1/10,000 Tesla - which is the SI unit for magnetic field strength.
NOTE: The part numbers shown in the schematic are reversed. A1309/A1308 are swapped.
Parts used:
-Atmega328P
-A1308KUA-1T
-A309KUA-9T
-LM317
Guide on burning bootloader / programming an Atmega328:

If you're buying brand new Atmega chips, you'll need to burn the bootloader before you can program them, but if you're just pulling the chip off an Arduino, you can skip that step.
