The element is a kind of magnetic sensor. It can detect the magnetic field and its changes, and can be used in various occasions related to magnetic field. Hall device has many advantages, such as firm structure, small volume, light weight, long life, convenient installation, low power consumption, high frequency, vibration resistance, no dust, oil, water vapor and salt fog Contamination or corrosion. The sensor has a m3 fixed mounting hole, which is easy to adjust and fix. By using a wide voltage m393 comparator, comparing the value transmitted by the hall element with the potentiometer value, it can directly output the high and low level, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA, and it is equipped with an adjustable precision potentiometer to adjust the sensitivity. The potentiometer rotates clockwise, the higher the sensitivity, and vice versa\u003c\/span\u003e \n\u003c\/div\u003e \n\u003cdiv style=\"font-size: 15px;\"\u003e\n    \n\u003c\/div\u003e \n\u003cdiv
