Comprehensive Analysis of Magnetic Sensors and Their Applications
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

In modern technology, a sensor refers to a type of component that can sense non-electrical quantities such as force, temperature, light, sound, and chemical components, and convert them into electrical quantities like voltage or current based on certain rules, or convert them into the … Read more
Understanding Magnetic Sensors
One of the four great inventions of our ancestors in China—the compass—is widely known. For modern sensor technology, it can be regarded as the predecessor of magnetic sensors. In today’s electronic age, magnetic sensors have a wide range of applications in motors, power electronics technology, the automotive industry, industrial automation, robotics, office automation, household appliances, … Read more
Basic Knowledge of Common Sensors
1 Basic Knowledge of Common Sensors The definition of a sensor is: “a device or apparatus that can sense the specified measurement and convert it into a usable signal according to certain rules, usually composed of a sensitive element and a conversion element.” A sensor is a detection device that can sense the information being … Read more
Summary of Various Sensor Principles
Sensors are components or devices that convert collected information into signals that can be processed by equipment. Humans act based on information obtained through vision, hearing, smell, and touch, and devices similarly control or process based on information obtained from sensors. Sensors collect and convert signals (physical quantities) such as temperature, light, color, atmospheric pressure, … Read more
Circuit Design and Selection for Current Detection Using Linear Hall Sensors
Hello everyone, I am Yi. Let’s continue with the design and selection of current detection circuits. In the previous article, we analyzed the resistance method for measuring current, and found that the limitation of the resistance method is that it introduces power loss, making it unsuitable for measuring large currents. For measuring large currents, Hall … Read more

Understanding Hall Effect Sensors: Principles, Applications, and Arduino Interface
Hall Effect Sensors are magnetic field sensors made based on the Hall effect. When a constant current flows through the internal Hall semiconductor chip, a potential difference, known as Hall voltage, is generated in the perpendicular direction. This Hall voltage changes with the strength of the magnetic field; the stronger the magnetic field, the higher … Read more
