Tips: What is the difference between the 6-axis and 9-axis IMU modes?

In 6-axis mode (gyro+accel), the azimuth angle is relative and will drift over time. In 9-axis mode (gyro+accel+magnetometer), the IMU system provides a stable, absolute magnetic heading, but requires a non-magnetic interference environment for accuracy.

Durability and long-term reliability

I’ve been using this wearable bluetooth IMU sensor for a while, and it has impressed me with its stable 100 Hz real-time data output and reliable wireless performance. The Bluetooth connection stays solid during movement, and the sensor’s rugged build—along with its IP65 waterproof rating—gives me confidence when using it outdoors or in tougher environments. Its ±500°/sec gyro range and ±8G accelerometer range provide accurate motion data for my project, and even after a few accidental drops, it still works perfectly. For such an affordable device, the durability and long-term reliability are outstanding, making it a great value for mobile motion-tracking applications.
