Overview

WitMotion BWT901CL is a compact 9-axis Bluetooth gyro inclinometer that fuses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer to output angles and quaternions in real time. It features Bluetooth 2.0 (≈10 m line-of-sight), an internal 3.7 V / 260 mAh Li-battery (≈4 h working time), and a built-in Kalman filter derived from aerospace attitude algorithms for high-stability, low-noise measurements. Free Windows PC software and Android/iOS apps provide configuration, live dashboards, data curves, 3D models, recording & playback, plus TXT export. A full development kit (drivers, manuals, demo videos, sample code for STM32/Arduino/51/Windows/Matlab) speeds integration for robotics, motion capture, rehab/sports tracking, and education.

Key Features

  • 9-axis IMU output: acceleration, angular velocity, magnetic field, angles & quaternion.

  • Kalman-based fusion: stable attitude in dynamic conditions; typical angle accuracy X/Y 0.05° (static), 0.1° (dynamic); Z 0.1° (calibrated).

  • Wireless & portable: Bluetooth 2.0, ≈10 m coverage; <50 mA working current; ~20 g.

  • PC & Mobile tools: real-time charts, 3D demo viewer (source code available on request), config menus, data logging & playback, TXT export.

  • Configurable ranges & I/O: selectable accel/gyro ranges, output frequency 0.2–200 Hz, 115200 bps serial TTL/USB, device address & content selection.

  • Compliance: TELEC, FCC, CE, ISO 9001.

Use Cases

Rehabilitation & patient motion analysis • Workplace injury prevention • Sports monitoring • Short-range wireless motion measurement • Education & R&D demos (3D attitude visualization).
