Why Choose WitMotion UK
Precision Motion Tracking, Simplified
The WT901BLE5.0 is a deployment-ready 9-axis Inertial Measurement Unit (IMU) designed for engineers, researchers, and developers who demand accuracy without the hassle of building a sensor stack from scratch. Combining a 3-axis accelerometer, gyroscope, and magnetometer, this module delivers highly stable, Kalman-filtered spatial orientation data directly to your PC, smartphone, or embedded system.
Seamless Developer Integration
While many developers initially search to buy PIR sensor UK for basic presence detection, advanced robotics and kinematic research demand precise spatial orientation. The WT901BLE5.0 bridges this gap with comprehensive SDK support for Arduino, Raspberry Pi, Python, and ROS. Whether you are developing autonomous navigation algorithms or monitoring structural vibrations, integration is frictionless.
Wireless Freedom & Reliability
Equipped with Bluetooth 5.0 technology, the sensor offers a stable transmission range of up to 50 metres in open environments. The built-in 250mAh lithium battery provides up to 40 hours of continuous operation, making it ideal for untethered field testing, drone telemetry, and wearable biomechanics research. Data can be visualised in real-time via the free WitMotion software or exported as CSV files for downstream analysis.

Customer Reviews
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.
Replaced a much more expensive industrial sensor with the WT901BLE5.0 for our vibration testing rig. The accuracy is spot on and having a built-in battery makes field deployment so much easier.
