RM3100 is a 3-axis magnetic sensor suite driven by PNI’s MagI2C ASIC interfaced through an SPI bus, eliminating the need for signal conditioning or an analog/digital converter. The RM3100 geomagnetic sensor is the highest performance sensor in its class with over 10 times better resolution and over 20 times lower noise than the leading Hall Eﬀect sensor. It makes precise magnetic field measurements, which enables accurate calculation of heading and orientation.
PNI’s geomagnetic sensor technology provides high resolution, low power consumption, large signal-noise immunity, a large dynamic range, and high sampling rates. Measurements are stable over temperature and inherently free from offset drift. The RM3100 incorporates both I2C and SPI interfaces for system design flexibility.
