FAQs
Are you connecting it to an Arduino, Raspberry Pi, or PC?
Yes, this sensor is fully compatible with PCs, Arduino, and Raspberry Pi systems. It easily interfaces using standard communication protocols and dedicated software for seamless data logging and testing.
What parameters does the WT901C-485 sensor measure?
The sensor measures 3-axis acceleration, angular velocity, Euler angles (pitch, roll, yaw), and magnetic field data. It functions as a comprehensive 9-axis AHRS and triple-axis tilt angle inclinometer.
How does Kalman filtering improve sensor performance?
Kalman filtering processes raw sensor data alongside dynamic fusion algorithms to eliminate noise and reduce long-term measurement drift. This ensures stable and accurate attitude tracking under both static and dynamic conditions.
