PNI Sensor’s Geomagnetic Sensors eliminate any “blur” in your magnetic field measurements

Based on PNI’s proprietary magneto-inductive technology, our sensors deliver high-performance resolution and repeatability with over 10 times better resolution and over 20 times lower noise than the leading Hall Effect sensor, enabling accurate calculation of heading and orientation. They provide high gain, high sampling rates, and no hysteresis. PNI’s magnetometers also do not require temperature calibration or current set-and-reset pulses before each measurement.

Why Geomagnetic Sensors

Geomagnetic sensors are used to measure the Earth’s magnetic field to provide absolute reference and heading. But a large challenge is the changing magnetic fields that temporarily distort the heading information, such as metal parts in furniture, a passing car, or nearby cell phones and computers. Compensating for these and other transient magnetic anomalies requires the geomagnetic sensor to be able to precisely distinguish between sensor noise (“blur”) and real changes in magnetic field. PNI’s geomagnetic sensors lead the field in their ability to reduce blur to establish the true magnetic field, outperforming other magnetic sensors by orders of magnitude.

Additionally, PNI’s Geomagnetic Sensors are simple to design in, and the peak current requirement is dramatically less than Hall Effect sensors. It isn’t surprising this patented technology has been proven across a wide spectrum of applications, including motion tracking, compassing, game control, TV and set-top box controllers, and magnetic field measurement.
