Hall Effect Sensor with LM393 Comparator, Motor Speed Test 32-step 1/16 D=Output CurrentA Hall effect sensor is a sensor that response to a magnetic field. When the hall sensor is put in a magnetic field the electrons running through will move to one side of the sensor. The sensor will then have one positive and one negative side and create a voltage, known as Hall voltage. Specification: Support 5 V 3. 3 V voltage input PCB board size: 30mmx15mm Signal detection sensitivity can adjust On board LM393 voltage comparator chip and hall
