Can I integrate the WT901BLE5.0 with my Raspberry Pi project?

Yes, absolutely. We provide a full Python SDK and detailed documentation specifically for Raspberry Pi and Linux environments, allowing you to parse the Bluetooth serial data effortlessly.

How accurate is the inclinometer data?

Thanks to the onboard Kalman filtering algorithm, the sensor achieves a highly stable angle accuracy of ±0.2 degrees on the X and Y axes, and ±1.0 degree on the Z axis under dynamic conditions.

Does this sensor support onboard data logging without a PC?

The WT901BLE5.0 transmits real-time data via Bluetooth to a connected device (PC, smartphone, or microcontroller) where it can be logged. For standalone offline logging to an SD card, please view our SD-series loggers.

Can I export the motion data to Excel?

Yes. The free WitMotion PC and mobile applications allow you to record your sessions and export the raw telemetry directly as standard CSV files, which open perfectly in Excel, MATLAB, or Python Pandas.

Is this shipped from within the UK?

Yes, all orders are dispatched directly from our UK warehouse, ensuring fast 1-3 day delivery and avoiding any unexpected import duties or customs delays.

An exceptional piece of kit for the price. We've integrated three of these into our custom rover chassis via ROS. The Kalman filtered output saves us a massive amount of processing overhead on the Pi.

Ordered on Tuesday, arrived Wednesday morning. The Bluetooth 5.0 connection is rock solid up to about 35 meters in our busy lab environment. The CSV export feature via the Android app is incredibly intuitive.

Very accurate sensor and the battery easily lasts a full week of intermittent testing. The only minor issue is the PC software UI feels a bit dated, though it functions perfectly well for calibration and logging.

I was looking for a reliable IMU for a biomechanics wearable prototype. The 200Hz output is fantastic and the 9-axis data is incredibly clean compared to the raw MPU6050s I was using previously.

Excellent value and superb technical support. I had a query regarding the Python SDK and the UK support team responded within hours with the exact code snippet I needed.

Great hardware. The magnetic calibration took a few tries to get right in our metal-framed workshop, but once set, the yaw drift is practically non-existent. Highly recommended for drone telemetry.
