Why Choose WitMotion UK
Engineering-Grade Motion Telemetry
Whether you are developing complex robotics navigation, conducting university rehabilitation research, or monitoring industrial vibration, the WitMotion WT901SDCL-BT50 delivers engineering-grade motion telemetry without the complexity of wired setups. As leading UK specialists, we know developers need reliable data. That is why this 9-axis IMU features an integrated Kalman filter, providing exceptional pitch and roll accuracy up to 0.2° at a blistering 200Hz output rate.
Seamless Developer Integration
Forget struggling with raw data interpretation. Our comprehensive SDKs for Python, C++, ROS, and Arduino get your project up and running in minutes. The built-in Bluetooth 5.0 ensures a stable 50-metre wireless range, while onboard SD card logging captures every micro-movement for downstream CSV analysis. While many engineers come to us to buy PIR sensor UK stock for basic presence detection, they quickly upgrade to our advanced IMUs for true spatial awareness and dynamic 3D kinematic tracking.
Built for Rigorous Field Testing
Designed for real-world deployment, the WT901SDCL-BT50 houses a robust 40-hour rechargeable lithium battery, making it perfect for prolonged field tests, drone flights, and vehicle dynamics monitoring. Fully UKCA and CE certified, it is the ultimate plug-and-play motion logger for British innovators demanding precision, reliability, and ease of use.

Customer Reviews
We deployed four of these in our university rehabilitation lab. The ROS integration was seamless, and the 200Hz output gives us the granular kinematic data we need without the cost of a full Xsens suit.
Incredible service from WitMotion UK. Ordered on Tuesday, arrived Wednesday. The Arduino SDK examples worked straight out of the box for my custom balancing robot.
The sensor hardware is brilliant and the Kalman filtering is remarkably stable. The PC software UI looks a bit dated, but since I pull the data directly via Python, it doesn't bother me at all.
We were looking for a reliable wireless logger for structural vibration testing. The offline MicroSD CSV logging feature is an absolute lifesaver when we lose Bluetooth range on large sites.
Used for drone telemetry testing. Excellent 9-axis data, just make sure you calibrate the magnetometer outdoors away from heavy metal benches to get a true heading.
The 40-hour battery life is a massive plus. I can run biomechanics tracking sessions all week without constantly worrying about charging the modules.
Unbeatable value for money. Getting Bluetooth 5.0, onboard logging, and ±0.2° accuracy at this price point is fantastic for our rapid prototyping workflow.
