Reading Time: 2 minutesArduino Team — February 8th, 2022 Magnetometers are devices that use various techniques to measure certain aspects of magnetism, including direction, strength, or relative changes. By combining these and applying some math, underground and other hidden structures can be discovered without the risk of damaging anything sitting below the sensor. This is why Markus Opitz decided […]
Reading Time: 2 minutesTurning a Tic Tac box into a portable magnetometer Arduino Team — January 24th, 2020 If you want a way to measure magnetic fields on the go, then look no further than this tiny device from Instructables user “rgco.” The portable magnetometer was made using just a couple of common parts, including an SS49E linear […]
Reading Time: < 1 minuteVisualizing magnetic fields in three dimensions with an Arduino magnetometer Arduino Team — July 25th, 2019 As humans, we can’t detect magnetic fields, but we take advantage of this phenomenon every day in the form of motors and various sensors. Even electrical wire produces a field when current flows through it. You can perceive magnetism […]
