Hello,

I am a student currently taking on a project which involves the measurement of shoulder motion of five volunteers. I am very interested in your product as I hope to place one IMU on the volunteers thorax, and another on each of their forearms. I hope that whenever the volunteer raises his forearm above his head, the forearm IMU will detect this as it is lifted above the thorax IMU. Hence, I was wondering whether your IMUs are suitable for my project. Can three IMUs (thorax and forearm IMUs) work in conjunction with each other as I desire? How long does the battery of the IMU last? - as I require the IMUs to last for about a week whilst they are attached to the volunteers. Can the IMUs can still submit data to me even if there is a great distance between myself and the volunteer? Finally, how would I be able to collect the data from the IMUs? Would the data I receive tell me whenever my volunteers has raised their arm?

Kind Regards,
Haran Thevaratnam

Hi,

The IMU sensors won’t interact with each other. You will need a microcontroller for example an Arduino Board.
The 3 IMUs will send data to the microcontroller depending on the communication interface of the IMU (UART, I2C, SPI).
You can either log the data in an SD Card using a Data Logging Shield for example, display the data in real-time with a display module for Arduino or send the data wirelessly to, let’s say your computer, using a Wifi Shield.
As for power, the choice of the battery specifications will depend on the current consumption of your entire setup : Microcontroller + 3 x IMUs + possibly Data logging shield/Wifi Shield/Display.
