QSense Wireless Motion Sensor

3D Orientation & Movement Tracking

Revolutionising the landscape of 3D orientation tracking, the QSense Wireless Motion Sensor emerges as a cutting-edge solution, seamlessly blending compact design with powerful functionality. This state-of-the-art wearable boasts a sophisticated 9 Degree of Freedom (9-DOF) Inertial Measurement Unit (IMU), a testament to precision and innovation.

At its core are pivotal MEMS sensors designed for unparalleled accuracy:

  1. Accelerometer (measuring linear acceleration): This sensor ensures meticulous tracking of linear movements, providing a granular understanding of an object’s acceleration in three-dimensional space.
  2. Gyroscope (measuring angular velocity): Immerse yourself in the intricacies of motion with the gyroscope, which meticulously gauges angular velocity. This feature allows for the precise measurement of rotational speed and changes in orientation.
  3. Magnetometer (measuring the Earth’s magnetic field): Unveiling a new dimension in tracking, the magnetometer enables the sensor to interpret the Earth’s magnetic field. This capability is integral for applications requiring orientation relative to the Earth’s magnetic poles.

Motion Sensing Data Outputs Tailored for Any Application

The QSense Wireless IMU Motion Sensor goes beyond mere data provision; it crafts an immersive experience.
