INTRODUCTION
The HCM370B/HCM375 B-N is a high-precision three-dimensional
compass with high resolution, strong noise immunity and stable
temperature offset. It uses advanced hard and soft iron calibration
algorithms and uses high-precision accelerometer for tilt
compensation, so that its roll angle can provide high-precision
heading information at any tool face of 360°. In the environment
with fixed interference, this product can still maintain a high
measurement accuracy. Long strip volume with a width of only
1.95cm. Reaching IP67 waterproof grade, it is more suitable for
drilling measurement. It has the characteristics of small size and
low power consumption, and can be quickly and conveniently
integrated into various products. The product can be ordered with
complete packaging products or circuit boards. This product
integrates a three-axis magnetic field sensor and a three-axis
acceleration sensor, calculates the course data in real time
through an industrial single-chip microcomputer with high
reliability and strong anti-interference capability, and uses a
three-axis accelerometer to compensate the course for a wide range
of tilt angles, which is a product with high performance and
stability. With small size and low power consumption, it is widely
used in handheld devices, mobile devices, antenna stabilization,
vehicles, system integration and many other fields.
