Working principle

The HAL856 UT-K three-axis linear and compass ICs use a combination of sensing elements and calibration to measure the Earth’s magnetic field. The device uses magnetic field sensors integrated in two triads, which measure the linear magnetic field components in the x, y, and z axes respectively. By carefully balancing the offset and gain, the device sets each sensor output\'s range to be equal to the Earth’s magnetic field range. A calibration algorithm is then used to minimize the nonlinearity of the magnetic field for each axis.

The HAL856 UT-K is also equipped with a digital processing unit (DPU) that is responsible for controlling the internal operations of the device. It performs low-level signal processing and PID loop correction, which is necessary to ensure a low noise signal and high accuracy. It can also be used to implement various customer-defined features.
