Hello, I'm Sam. Check what happens. And RF (receiver) of diagram display to LED lights turn on. Generally digital Hall effect sensors have an open-collector, or open-drain output, so an external pull-up resistor is required. Because of its simplicity, low cost, and fast turnaround time, it is an indispensable characterization technique in the semiconductor industry and in research laboratories. Sideways or slide-by detection is useful for detecting the presence of a magnetic field as it moves across the face of the Hall element within a fixed air gap distance for example, counting rotational magnets or the speed of rotation of motors. The output state of a Hall sensor normally switches between zero and Vcc, so some other form of external amplfication would be required. Also to ensure linearity, high field strength magnets are required that produce a large change in field strength for the required movement. When the device is placed within a magnetic field, the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers, electrons and holes, to either side of the semiconductor slab.
