The Honeywell HMR3000 digital compass module manual provides specifications, wiring, and communication details for the three‑axis sensor.
The HMR3000 is a three‑axis digital compass module that outputs heading, pitch and roll data using a solid‑state magnetoresistive sensor. It communicates via RS‑232 or RS‑485 using ASCII characters and supports standard NMEA sentences as well as proprietary formats.
The module is designed for marine, drilling, avionics, GPS integration and other precise navigation applications. It offers high accuracy (0.5°), fine resolution (0.1°), fast response (up to 20 Hz) and a wide tilt range (±40°) while consuming less than 25 mA, making it suitable for battery‑powered installations. This manual is written in Chinese.
| Heading accuracy | 0.5° |
|---|---|
| Resolution | 0.1° |
| Response time | up to 20 Hz |
| Power consumption | <25 mA |
| Tilt range | ±40° |
The module can output the standard NMEA sentences HDG, HDT and XDR, as well as proprietary formats HPR, RCD and CCD.
The sensor can be powered from a regulated 5 V supply or an unregulated 6 V–15 V source.
