High Precision 3 Axis Electronic Compass
HCM605B Three-Axis Electronic Compass
The HCM600/HCM605 series is a dynamic, high-precision 3-axis electronic compass that integrates a three-axis accelerometer, three-axis gyroscope, and three-axis magnetic sensor. Utilizing a 32-bit high-speed processor, it calculates roll, pitch, and heading angles in real time with three working modes: pure compass mode, 9-axis fusion mode, and 9-axis fusion anti-jamming mode (anti-temporary interference).
Advanced calibration algorithms for hard iron and soft iron compensation ensure high-precision heading angles within ±180°, even at large tilt angles. With a narrow width of only 1.95 cm, this compass offers exceptional performance, reliability, compact size, and low power consumption. Available as a complete product with IP67 waterproof housing or as a compact module.
