Perfect demo of how hall effect sensors operate with a magnetic field being applied. Exactly how abs braking system measures wheel rotation in an alternating magnetic field
I am brainstorming ways to use one or more hall effect sensors to create some sort of biofeedback for myself (I know very basic but definitely effective). Instead of bringing a magnet close to the sensor I would like to get the 'reverse effect directly from a person's physique (me) and so on. it would be useful to be able to discharge the electromagnetic fields caused by the use of smartphones, tablets, etc. Do you understand my point of view?
