By certification 
SEC340 is a high accuracy 3-Axis digital compass with 40° Dip angle compensation.The SEC340 sensor module combines 3-axis magneto sensors with a 3-axis MEMS accelerometer in a single temperature- and noise-stabilized design that's inherently free of offset drift. Using Mems's proprietary hard- and soft-iron correction algorithms,Mems calibrate out most magnetic anomalies for repeatable, high-resolution measurement across a broad range of navigation and tracking applications.A patented tilt compensation make SEC340maintain high accuracy heading even in 40° Dip angle.
The small sizeand low power consumption makeSEC340 suitable for size sensitive measurement systems. SEC340is the best choice for applications that require highperformance and low cost.
