Description
The AK8973B-L is an electronic component IC chip that belongs to the geomagnetism detection type electronic compass. It is widely used as an optimal built-in electronic compass for mobile phones and handy terminals. The AK8973B-L integrates magnetic sensors for detecting geomagnetism in the X-axis, Y-axis, and Z-axis, and an arithmetic circuit for processing the signal from each sensor. The IC chip outputs four data in total as 8-bit digital values respectively: 3-axis magnetic sensor measured values and temperature sensor read value. By processing the magnetic sensor measured values with an external CPU, azimuth data can be obtained.
