CompassPoint PRIME
PNI Sensor Corporation's Prime 3-axis digital compass combines PNI's patented magneto-inductive sensors with a 3-axis MEMS accelerometer in a low-cost compass that provides accurate heading and tilt readings, even at very high and low latitudes.
PNI's advanced hard and soft iron correction algorithms allow for compensation of magnetic distortions inherent in the user's system, resulting in reliable and consistent readings. Other 3-axis systems don't provide true 3-D soft-iron correction, resulting in unreliable, inaccurate headings in the presence of soft-iron distortions caused by any ferrous metal.
The Prime excels in low power consumption by combining PNI's inherently low power consumption magneto-inductive sensors with intelligent electronics that result in current consumption of typically 18 mA when sampling and <1 mA when not sampling.
The Prime represents a tremendous value by combining a low price with the Prime's heading accuracy (even at extreme latitudes), low power consumption, and PNI's advanced magnetic distortion correction algorithms. The Prime is an ideal component for cost-sensitive products that historically could not afford to incorporate such a well-featured digital compass
