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.

Reliable high precision compass sensor for buoy tracking

Ordered a few units of this high precision compass sensor for a marine telemetry buoy array project last month. Runs fine off our standard 12V regulator system. The plastic enclosure feels durable enough and the heavy cable gland keeps the sea spray out. Had to recalibrate once near iron frames but accuracy is spot on now.
