Why Choose WitMotion UK
The WitMotion WT901BLE5.0 is an engineering-grade 9-axis Inertial Measurement Unit (IMU) designed to deliver uncompromising accuracy for UK developers and researchers. Combining a high-precision accelerometer, gyroscope, and magnetometer with a built-in inclinometer, this module streams real-time, Kalman-filtered orientation data directly to your preferred platform via low-latency Bluetooth 5.0.
Seamless Developer Integration
We know that hardware is only as good as its software ecosystem. The WT901BLE5.0 comes with extensive SDK support, making it incredibly simple to integrate into Arduino, Raspberry Pi, Python scripts, or full ROS navigation stacks. Whether you are upgrading an autonomous drone's telemetry or looking to buy PIR sensor UK stock and motion modules for a comprehensive security prototype, this IMU provides the robust foundational data your project demands.
Standalone Wireless Logging
Equipped with a built-in 250mAh rechargeable lithium battery, the WT901BLE5.0 can operate entirely untethered. Log high-frequency 200Hz motion data directly to the free iOS/Android apps, or stream it to your PC for real-time 3D dashboard visualisation and CSV export. It is the perfect tool for vehicle dynamics testing, human gait analysis, and remote vibration monitoring where traditional wired sensors simply cannot reach.

Customer Reviews
Integrated this into our lab's ROS navigation stack for a tracked robot. The Python SDK worked out of the box, and the 200Hz Kalman-filtered data is incredibly stable compared to raw MEMS chips we used previously.
Excellent piece of kit for the price. We use it for gait analysis in our biomechanics research. The Bluetooth 5.0 range is solid across the entire lab, and exporting to CSV via the app is painless.
Great IMU with very accurate pitch and roll. The yaw drifts slightly if you don't calibrate it perfectly away from metal desks, but once calibrated properly, it holds its heading very well. Delivery was next day as promised.
I bought this to log vibration and orientation data on a UAV prototype. The 20g weight is perfect, and the built-in battery saves me having to wire up a separate BEC. Highly recommended for drone builders.
Much easier to deploy than the Adafruit breakouts we were using. Having the enclosure, battery, and Bluetooth all integrated means we can slap it onto a test rig with double-sided tape and get data instantly.
The technical documentation is surprisingly good. I had it streaming quaternions into my custom C++ application within an hour. The CE/UKCA marks are also essential for our university procurement compliance.
Brilliant sensor, very reliable data logging. My only minor gripe is that the PC dashboard is Windows only, but I just use the Python script on my Mac so it's not a major issue. Good value for money.
