HCM370B/HCM375B High Precision 3D Electronic Compass Sensor with Tilt Compensation
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.
