Here are some technology key words that often appear when you use sensors.
Tri-axis magnetic sensor
A tri-axis magnetic sensor is a sensor that can detect a magnetic field from any direction (X, Y, Z axes) applied to the sensor. In AKM, it is a group of products called "3-axis Magnetic Sensor" and "3D Magnetic Sensor."
Magnetic flux density
Magnetic field strength (H) multiplied by magnetic permeability (μ) is called magnetic flux density (B). The unit of magnetic flux density is generally Tesla [T].
In the case of a sensor with digital output, it refers to the minimum value of the magnetic field change required to change the output by one code. For example, in the case of a sensor whose sensitivity is "1.1 [μT / LSB]", when a magnetic field change of 1.1 [μT] occurs, the sensor's output code changes for the first time. This is synonymous with the resolution.
