Electronic compass HEC303

3Dtilt-compensated

The HEC303 high-precision electronic compass is composed of an industrial-grade single-chip microcomputer with high reliability and strong anti-interference ability, and a high-precision magnetic sensor and drive chip. At the same time, it integrates the hard magnetic and soft magnetic calibration algorithms of BWSENSING patented technology, and uses a three-axis accelerometer to compensate the tilt angle, so that accurate heading data can be provided in extremely harsh environments. Through the optimized extended Kalman filter algorithm, the product outputs high-precision attitude information in real time. Integrating a new twelve-position calibration algorithm, calibration is more convenient and flexible.
