SEC380 High-Precision Cost-Effective Inclination Compensation 3D
Electronic Compass RS232/RS485/TTL Optional
Introduction:
SEC345 is a cost-effective three-dimensional electronic compass,
which can meet the needs of different application scenarios. It can
easily and quickly integrate the functions of the electronic
compass into various systems. The product adopts the patented hard
iron and soft iron calibration algorithm, so that it can still
provide high-precision heading information when its inclination
reaches 40 °. It has the advantages of small volume and low power
consumption.
