Overview

High precision compass sensor is an industrial-grade horizontal azimuth module delivering 1° heading accuracy with 0.1° resolution across the full range. It has magnetic compensation with soft/hard-iron calibration and an anti-interference design to maintain stable heading even with ±5° tilt. Running on 12 V, SUCH compass sensor offers RS232, RS485, TTL, and RS422 outputs for easy integration. Rugged IP67 (IP68 optional), compact, and low-power, it suits harsh −40 to +85 °C environments. Typical applications include solar tracker orientation, AGV carts and medical devices, railway/locomotive monitoring, construction machinery angle control, building tilt/structural health monitoring, and ship navigation attitude measurement.

FAQ

Q1: What’s the difference between accuracy and resolution? ❯

Resolution (e.g., 0.1°) is the smallest step the output can change by. Accuracy (e.g., ±1°) is how close the reported heading is to the true heading after proper calibration and installation.

Q2: 2D vs 3D compass—what’s the difference? ❯

A 2D compass assumes the sensor is level; tilting causes errors. A 3D (tilt-compensated) compass uses accelerometers (and sometimes gyros) with magnetometers to maintain accurate heading while pitching/rolling.

Q3: Do I need to set magnetic declination? ❯

If you need true north, yes—apply local declination to convert magnetic heading to true heading. If magnetic north is acceptable (many robotics/AGV cases), you can leave declination at 0.
