Hall sensors are widely used in automobiles, one of which is as oil level sensors. This sensor has a sophisticated structure and consists of a circuit board, a magnetic element, a Hall element, a bracket, a rotating rod and a float. They work together to accurately measure the oil level in the tank by sensing the position change of the magnetic element through the Hall element. This design is not only structurally stable, but also accurate in measurement, providing reliable oil level monitoring for automobiles.
Recommended model: HS95A high-sensitivity linear Hall chip
HS95A is a small, general-purpose, linear Hall effect sensor. Its output signal level is determined by the strength of the magnetic field applied to the sensitive surface of the device and changes proportionally with the magnetic field strength. When in zero magnetic field conditions, its output voltage is half of the power supply voltage. For T0-92S package products, when the S pole appears on the marked surface, the output voltage will increase linearly with the increase of magnetic field strength, and the N pole will make the output voltage decrease linearly with the increase of magnetic field strength. The induction polarity of SOT23 package products is just the opposite. It has the characteristics of low noise output and no longer requires external filtering. It also includes thin film resistors to improve temperature stability and accuracy. The operating temperature range is -40℃ to 150℃, suitable for various commercial and industrial environments.
