Hall sensor is a magnetoelectric conversion device based on Hall effect, which is widely used in industrial automation, automotive electronics, measurement and control, and other fields. According to different working principles and application scenarios, commonly used Hall sensors can be divided into the following types:
1.Switching Hall sensors.
A switched Hall sensor is a sensor with a digital output that flips when the magnetic field reaches a certain strength. This type of sensor is usually used to detect the presence or absence of a magnetic field or the direction of the magnetic field, such as motor rotor position detection, door and window switching, etc.
2.Linear Hall sensors.
A linear Hall sensor is a sensor whose output signal is linearly related to the strength of the magnetic field, and is usually used to measure the strength or position of the magnetic field. This kind of sensor has the characteristics of high precision, high stability and high reliability, and is widely used in motor control, position measurement, angle measurement and other fields.
3.Rotate the Hall sensor.
A rotary hall sensor is a sensor that can measure the angle of rotation and rotational speed, and is commonly used in motor control, vehicle speedometers, flow meters, and other fields. This sensor can be combined with multiple Hall elements to achieve multi-pole magnetic field detection, resulting in more accurate measurement results.
4.Hall current sensors.
A Hall current sensor is a type of sensor that measures current based on the Hall effect, and is typically used to measure DC and AC currents. This kind of sensor has the characteristics of wide measurement range, high accuracy and fast response speed, and is widely used in power monitoring, energy management, industrial automation and other fields.
5.Hall-effect fluxgate sensors.
A Hall-effect fluxgate sensor is a sensor based on the Hall effect and fluxgate principle to measure weak magnetic fields and magnetic fluxes. This sensor has extremely high sensitivity and resolution and can measure very small changes in the magnetic field, and is commonly used in geomagnetic measurements, biomedicine, and other fields.
In conclusion, there are many types of Hall sensors, and different types of Hall sensors have their own characteristics and application scenarios. In practice, it is necessary to select the right Hall sensor for the specific needs to meet the requirements of measurement and control.
