Function introduction

    The Hall sensor is a magnetic field sensor based on the Hall effect. When the magnet is above the Hall sensor, the Hall sensor detects the magnetic field and will output a low level. The triode Q1 will no longer be turned on, and the three-stage tube Q2 will be turned on. During the conduction process, the current flows through the inductor L1 and will generate a magnetic field in L1. The direction of the magnetic field is determined by the direction of the current flowing in the coil, following the right The hand spiral rule is that when the magnetic field of the coil and the magnetic field of the magnet repel each other, the magnet will be pushed away. After the magnet is pushed away, the Hall sensor will no longer detect the magnetic field and will output a high level. Q2 will no longer be conductive, and the remaining electric potential on L1 will dissipate through D1. From this way, the electronic swing will continue to swing.
