Jewell ECV eCompass Series Description：

Datasheet User's Guide Installation Quick Guide

The ECV eCompass Series is a 3D electronic compass providing stable azimuth, pitch, and roll measurements in dynamic conditions. As an enhanced version of our ECG Series, the ECV includes a full suite of precision, 3-axis, MEMS sensors, and an optional dual-axis electrolytic tilt sensor, for the ultimate in near-level accuracy. A high-performance microcontroller orchestrates the fast measurement sequence, sensor calibration adjustments, frame-of-reference translations, trigonometric calculations, and advanced signal processing required to provide accurate heading, pitch, and roll outputs.
