The main function of an oscilloscope probe is to bring the voltage signal being measured from the measurement point into the oscilloscope for measurement. Ideally, the oscilloscope probe should have no effect on the measured signal, but in reality, its long cable inevitably has stray inductance, capacitance, and resistance. Therefore, they will affect the oscilloscope’s … Read more

01 Introduction The Hall effect sensor is a type of sensor that detects the presence of a magnetic field. Similar to the linear Hall sensor introduced earlier, it does not provide a linear output of magnetic field strength but can only indicate whether a magnetic field is present. 02 Principle This Hall effect sensor uses … Read more
01 Introduction The linear Hall sensor is a type of sensor that utilizes the principle of the Hall effect, which generates a potential difference as the magnetic induction intensity increases through its linear region. It is commonly used for measuring physical quantities, such as fuel gauges and liquid level meters. The joystick used in game … Read more
Among various sensing technologies, the most commonly used and widespread method for detecting magnetic fields is the Hall effect method. Based on the Hall effect, many Hall effect sensors or transducers have been found in various applications, primarily used for sensing proximity, speed, current, and position. This is due to the ability to construct Hall … Read more
The potential difference generated by the Hall effect is very small, often only a few microvolts. Therefore, Hall sensors often have a built-in high-gain operational amplifier and may be combined with other system circuits based on overall requirements. The overall architecture is shown below. Typically, the final output signals from Hall sensors can be either … Read more

Overview of Magnetic Sensors Magnetic sensors have basic characteristics such as non-contact measurement, high reliability, robustness, and high measurement sensitivity. The magnetic field can penetrate many non-metallic materials, triggering the exchange process without direct contact with the target object. By using magnetic conductors (such as iron), the magnetic field can be conducted over longer distances, … Read more
