IMU Sensor STT IWS Hardware

Synchronization: A key factor in order to achieve high-quality data for biomechanics. All measurements are automatically timestamped in order to guarantee an actual synchronization. The sync is ultimately handled and guaranteed by the Wi-Fi network.

Enhanced Accuracy:  Additional sensors and indicators are used to calibrate the measurements acquired by the primary sensors to increase the accuracy:

• The board includes a temperature sensor, used for sensor calibration purposes All internal sensors are calibrated in temperature.
• The board includes a humidity sensor as well.
• The sensor internally checks battery health parameters like remaining voltage, current measurement, remaining time, etc.

Communication Interfaces: 

• STT-IWS sensors can communicate in different ways:
• 1x USB connection handles both communication and power.
• 1x Serial port, compatible with RS-232.
• Wi-Fi protocol for wireless communications (protocol used is 802.11n @ 5 GHz, both as AP or client mode).
• SD card for internal storage (used for offline recording – will be enabled in upcoming iSen versions).

Drift Correction:  An on-board AHRS sensor fusion algorithm combines inertial and magnetic readings to minimize drift and provide an orientation relative to Earth. Each device is individually calibrated using robotic equipment to achieve the highest accuracy.

Power: The STT-IWS can be powered in three different ways: with its own internal battery,  with the USB connector, or with an external power supply.
