HCM600/HCM605 is a dynamic and high-precision 3 axis electronic compass, which integrates three-axis accelerometer, three-axis gyroscope and three-axis magnetic sensor. The roll an gle, pitch angle, and heading angle data are dynamically calculated in real time through a 32b it high-speed processor. , it has three working modes: pure compass, 9-axis fusion mode and 9-axis fusion anti-jamming mode (anti-temporary-interference), using a three-axis accelerometer and a three-axis gyroscope to compensate heading angle error caused even by big tilt angle, and adopting hard iron and soft iron calibration algorithms, so that the roll angle can still provide a high-precision heading angle within the range of ±180°. It is long strip shape with widt h of only 1.95CM. with high performance, reliability, small size and low power consumption, its suitable for measuring attitude and heading angles in many fields such as antenna stability, vehicles, and drones. User can order complete product with housing (up to IP67 waterproof level) or compass module.
