The Hall element is actually a magnetic sensor, which can be used in many places. The magnetic sensor can effectively sense the change of the magnetic field. After all, this component is not only small in size, but also has a long life and is very convenient to install. In addition, this kind of use environment is still very powerful. Not only is it not afraid of vibration, but also dust and oil are no problem, and it will not affect its normal use. It can be said that this kind of precision is relatively high. They are all used, and are divided into switching devices and linear devices according to function furnaces, and the detection objects of the two are still different.

The Hall element is used directly and indirectly in the detection process, that is, the direct detection of the magnetic field characteristics, and this switching device also uses the magnetic field as a carrier to carry out more pressure positions and so on. detection and control. For example, the Hall element, when detecting how many turns the motor rotates, usually uses a magnet to generate a voltage difference, so as long as there are a few voltage differences, you can know how many turns it turns, so the effect of this use is still very obvious. For example, in the green ignition system, this kind of sensor is used as an ignition pulse generator, which can not be affected by the environment, and can be accurately ignited to better control the primary current. The principle is that with the change of the magnetic field, a voltage measurement is generated in the semiconductor layer to control the ignition. This advantage of no maintenance and no preservation has a great impact on the performance improvement of the engine.
Hall elements have a very wide range of applications, such as the application of the mecha system in taxis, which can better calculate the mileage. For example, when the wheel turns a circle, all software can detect the signal for calculation. The amount displayed by the single chip calculation will also increase, which is very convenient indeed. In addition, an or current can be formed on the inverter, so that the output voltage is proportional to the current, so that it can be used better. This principle is simple and easy to use and is widely used in inverters.
