HCM370B High Accuracy 3D Digital Compass With Soft Magnetic
Calibration
Product Description:
HCM370B/HCM375B-MP is a high-precision 3D compass with high
resolution, strong anti-noise ability, and stable temperature
drift; it adopts advanced hard iron and soft iron calibration
algorithms, and uses high-precision accelerometers for tilt
compensation, allowing it provide high accurate heading at any roll
angle in 360°. In an environment with fixed interference, this
product can provide high accurate measurement.
Long strip shape, the width is only 1.95CM. It is IP67 grade and is
more suitable for drilling measurement; it is small and consumes
low power, which can be quickly and conveniently integrated into
various products. Both complete product and PCBA of the senor are
available.
This product integrates a three-axis magnetic field sensor and a
three-axis acceleration sensor. It uses an industrial single-chip
computer with high reliability and strong anti-interference ability
to calculate heading data in real time, and uses a three-axis
accelerometer to compensate for a wide range of tilt angles. With
high-performance, high-stability products, small size and low power
consumption, make it suitable for many fields such as handheld
devices, mobile devices, antenna stability, vehicles, and system
integration.
