Honeywell compass module analog HMR3500-CH digital compass module replace Honeywell HMR3500
Product description
The domestic version of HMR3500-CH three-dimensional electronic compass is available. This product can completely replace the imported version. Its hardware is 100% imported from the United States. The software design and imported version can be completely matched. It can be directly installed and used without changing any hardware size or software program.
HMR3500-CH compass module is a three-axis digital compass solution with a customizable coordinate system that can be installed at any predetermined heading. Combines data from three heterogeneous magnetoresistive sensors with data from three MEMS accelerometers to provide compass heading, pitch, and tilt angle information.
HMR3500-CH provides hard iron and soft iron magnetic compensation algorithms to correct the effects of magnetic field distortion. In addition, a world magnetic field model is provided, which can automatically provide magnetic declination compensation relative to true north (geographic north).
RION Technology guarantees the excellent quality of its products by introducing innovative solid-state magnetic sensor solutions. As promised, these are products with high reliability and best performance. RION Technology's magnetic sensor products can provide you with the most authentic and reliable solutions, which you can trust.
