Linear Hall sensors  are mainly used for the measurement of some physical quantities. 1. Current sensor: Because there is a magnetic field inside the energized solenoid, its size is proportional to the current in the conductor, so the Hall sensor can be used to measure the magnetic field to determine the current in the conductor. Using this principle, a Hall current sensor can be designed. The advantage is that it does not make electrical contact with the circuit under test, does not affect the circuit under test, does not consume the power of the measured power supply, and is particularly suitable for large current sensing. 2. Displacement measurement: The two permanent magnets are placed opposite to each other, and the linear Hall sensor is placed in the middle. The magnetic induction intensity is zero. This point can be used as the zero point of the displacement. When the Hall sensor is used to make a △Z displacement on the Z axis, the sensor has A voltage output, the v

According to the nature of the detected objects, applications of  Hall Sensor  can be divided into: direct application and indirect application. The former is to directly detect the magnetic field or magnetic property of the object under test, and the latter is to detect the magnetic field set by the object under inspection, and use this magnetic field as a carrier of the detected information, through which many non-electrical, non-magnetic The physical quantity. Forces, moments, pressures, stresses, positions, displacements, speeds, accelerations, angles, angular velocities, revolutions, rotation speeds, and times when the operating conditions change, for example, are converted into electrical quantities for detection and control.

Hall sensors are widely used in our daily lives. For example, in a mobile phone with a flip cover or a slide cover, a device for detecting opening or sliding of the mobile phone cover is a Hall sensor; for example, on a computer keyboard, a scroll key for moving a cursor is a Hall sensor. Also, there are Hall sensor applications in parts that require motors, such as automotive gearboxes, power windows and doors. We are dealing with Hall sensors in everyday life.  Hall effect sensor circuit  is widely used. Hall sensor applications have different fields, so the requirements of each market are not the same. The main requirements for Hall sensors in the mobile phone market include size, power consumption and adjustable thresholds. For industrial and automotive applications, Hall sensors must first meet industry or automotive certification requirements for devices such as safety, stability, and temperature ranges to achieve corresponding levels. Low cost hall effect sensor  can be s

As many people know, the higher the degree of automation in cars, the more microelectronic circuits are, and the more they are afraid of electromagnetic interference. In the car, there are many lamps and electrical devices, especially the headlights with large power, air conditioning motors and wiper motor will generate inrush current during switching, causing arcing of the mechanical switch contacts, resulting in greater electromagnetic interference signal. Using power  Hall IC  switching circuits can reduce these phenomena. For example, position, displacement, angle, angular velocity, rotation speed, etc., and these variables can be transformed twice; pressure, mass, liquid level, flow rate, flow, etc. can be measured. The current Hall devices can withstand a certain degree of vibration, and can work in the range of minus 40°C to minus 150°C. All the seals are not contaminated by water and oil and can fully adapt to the harsh working environment of automobiles. Hall sensor
