In terms of usage, only temperature sensors have a slight advantage, but Hall effect sensors have also been used in a wide range of devices in domestic and commercial applications, including DVDs, CDs, memory drives, automatic toys, mobile phones, car compasses, and car ignition systems. You ...
with current from a battery terminal 54 via a voltage regulator 52 and a current regulator 50, and the output signal from the sensor is amplified at 58 and fed to a Schmitt trigger 60 to switch a set of transistors 76, 78, 82, the latter controlling the current in an ignition coil 84...
Significant role of quantised Hall effect with development of transistors Hall effect observed in two dimensional systems of electrons at low temp. and strong magnetic field Hall resistance is quantised and is no longer increasing linearly with magnetic field (ν = 1, 2, 3, etc.). The Integer...
