HCM380B/HCM385B-MP is a cost-effective 3D electronic compass. It adopts 24-point calibration method, which has stronger anti-interference and easy operation, and uses high-precision accelerometer for tilt compensation, so that it can provide high-precision heading information at any tool surface at roll within ±180 °For fixed interference, it can still provide high-precision measurement data, RS232, RS485, TTL multiple communication interface methods are optional.
The product integrates a three-axis magnetometer and a three-axis accelerometer, with high resolution and strong anti-noise capability. It is a high-performance, high-stability product with small size and low power consumption; It is widely used in many fields such as handheld devices, mobile devices, antenna stabilization, vehicles, and system integration. The product can be ordered with a sealed package or a circuit board.
