BWSENSING SEC345-M 3D Electronic Compass & Tilt Sensor, 1° Accuracy, RS485 Modbus, Magnesium Alloy Shell, IP67
The BWSENSING SEC345-M is a high-precision 3D electronic compass and tilt sensor integrating MEMS-based 3-axis magnetometer and accelerometer technology. It delivers compensated heading data via an industrial RS485 Modbus interface, making it suitable for integration with PLCs, industrial controllers, and embedded systems like Raspberry Pi or Arduino with RS485 shields.
Features
- High-precision 3D electronic compass with 1° RMS heading accuracy and 0.1° resolution.
- Integrated tilt compensation up to ±40° for accurate heading in sloped installations.
- Industrial RS485 Modbus communication interface for stable, long-distance data transmission up to 115200 baud.
- Robust magnesium alloy housing with IP67 protection rating for operation in harsh environments (-40°C to +85°C).
- Onboard hard and soft iron calibration algorithms for reliable performance in electromagnetic interference.

The SEC345-M utilizes a sophisticated MEMS-based sensing system combining a three-axis magnetometer and a three-axis accelerometer. This fusion provides real-time digital heading output from 0° to 360°, automatically compensating for sensor tilt up to ±40 degrees. The integrated calibration routines mitigate errors caused by permanent (hard iron) and induced (soft iron) magnetic distortions, ensuring measurement integrity in challenging field conditions.
Designed for industrial durability, the sensor features a sealed magnesium alloy shell rated IP67, protecting against dust and temporary water immersion. Its RS485 interface supports the Modbus RTU protocol, enabling easy daisy-chaining and integration into existing SCADA, automation, or navigation systems. The included 1.5-meter cable with metal connector facilitates secure installation.
