The RM3100 was previously used in navigation fields such as land and ocean mapping, sonar positioning, and robotics. Now consumer products can also utilize the same precision RM3100, said Becky Oh, President and CEO of Precision Navigation. The RM3100 geomagnetic sensor measures the geomagnetic field to deliver accurate, reliable, and smooth motion tracking. RM3100 is an industrial-grade product designed for precise and stable azimuth measurement applications. It offers a measurement accuracy of less than 10nT—less than 0.1% of the Earth's magnetic field—making it ideal for applications requiring accurate heading or azimuth detection. Its performance exceeds that of existing MEMS or Hall effect sensors by more than 20 times.The RM3100 is part of Precision Navigation’s geomagnetic sensor family and features three advanced coil-type magnetic sensors along with ASIC driver chips. It has been enhanced in gain, resolution, and power efficiency, and supports both SPI and I2C interfaces for flexible integration. Leveraging Precision Navigation’s proprietary technology, the RM3100 delivers 23 times higher resolution and 27 times lower noise compared to traditional Hall-effect magnetic sensors, enabling precise heading data across diverse applications.Color: As Shown Material: PCB Package Contents: 1 x RM3100 Three-Axis Magnetic Field Sensor Note: Other items not included.
