Hall sensors are used to detect and measure magnetic fields - the output signal level is proportional to the magnetic field intensity. This Hall Sensor from Waveshare uses an LM393 wide-range voltage comparator and features adjustable sensitivity and a signal output indicator LED. Comes with a 4-pin jumper cable for connecting to your development board.
