W2 Inertial Measurement Unit

Quick Overview

The W2 IMU offers untethered transmission of sensor data via Bluetooth in a single compact package. An integrated rechargeable battery allows for up to 5 hours of power when using Bluetooth and can be charged via USB. The W2 has integrated Gyros, Accelerometers, Magnetometers and atmospheric pressure sensor. The gyros can be configured to ±250, ±500, or ±2000°/sec and ±2g, ±4g/±6g, ±8g, and ±16g for the accelerometers. The device is 1.58 x 1.32 x 0.6" and can be either screw mounted or easily strapped down with the built-in strap bars..

  • Miniature package
  • Transmits wirelessly via Bluetooth
  • Great for space and weight restricted applications
  • Integrated rechargeable battery
  • Up to 5 hours operation with internal battery.
The W2 IMU is the second generation Memsense wireless IMU that provides wireless serial digital outputs of triaxial acceleration, angular rate and magnetic field as well as temperature and barometric pressure via the Bluetooth™ wireless protocol. The inertial outputs are compensated over temperature for bias, scale factor, and cross-sensitivity. The accelerometers and gyroscope within the W2 IMU can be configured to different dynamic ranges over the wireless connection with a simple command structure. The available ranges for the gyroscopes are ±250, ±500, or ± 2000 °/sec and ±2g, ±4g, ±6g, ±8g, and ±16g for the accelerometers.

With the Bluetooth™ capability, the IMU can communicate with a wide variety of  hosts, such as PCs, tablets, phones, and embedded systems. The range of transmission can be affected by the environment, but typical range capabilities are on the order of 60 feet.

An integrated rechargeable battery allows for up to 5 hours of power and can be charged via micro USB which makes the W2 IMU a convenient option for inertial measurement applications.

The device measures 1.58" × 1.32" × 0.60" and can be either screw mounted or easily strapped down with the built-in strap bars. Multiple Wireless IMUs can be utilized simultaneously allowing inertial motion capture of multi-segmented objects common in human motion analysis. The miniature size, wireless multiple device connection and configurability of the W2 IMU makes it an exceptional sensor choice for applications such as human motion analysis, biomechanics, or animation.
