Cars with anti-lock braking system (ABS), anti-skid brick control (ASR), four-wheel drive or with electronic stability program (ESP) are equipped with Hall acceleration sensors in addition to the wheel sensors to measure The longitudinal and lateral acceleration of the car while driving.
The Hall element is a magnetic sensor based on the Hall effect, which has developed into a variety of magnetic sensor product families and has been widely used. They can be used to detect the magnetic field and its changes, and can be used in various occasions related to the magnetic field. The Hall device is based on the Hall effect. Hall devices have many advantages. They have a solid structure, small size, light weight, long life, easy installation, low power consumption, high frequency, vibration resistance, and are not afraid of pollution or corrosion such as dust, oil, water vapor and salt spray.
Movement mode between Hall device and working magnet
The Hall linear device has high precision and good linearity; the Hall switching device has no contact, no wear, clear output waveform, no jitter, no rebound, and high position repeat accuracy. Hall devices with various compensation and protection measures have a wide operating temperature range. According to the function of Hall devices, they can be divided into: Hall linear devices and Hall switching devices. The former outputs analog, and the latter outputs digital.
