On-board magnetic sensors are magnetic sensors that are installed and tested on a circuit board. Functioning as transducers, these sensors convert variations in magnetic fields into electrical impulses, which are utilized to measure and identify changes in the magnetic field. On-board magnetic sensors are capable of detecting magnetic fields to provide precise measurements of direction, orientation, and position.

The primary categories of on-board magnetic sensors include hall effect sensors, squid (superconducting quantum interference device) sensors, magneto resistive sensors, and others. Hall effect sensors, a specific type within this range, have the capability to ascertain both the direction and strength of a magnetic field generated by electromagnets or permanent magnets. Their output adjusts proportionally to the power of the measured magnetic field. These sensors come in variants suitable for low-field (< 1 microgauss), earth field (1 microgauss to 10 gauss), and bias magnetic field (>10 gauss) applications. They find application in diverse industries such as automotive, healthcare, consumer electronics, aerospace and defense, industrial, and more.Asia-Pacific was the largest region in the on-board magnetic sensors market in 2025.
