Hello All,
Apologies in advance for sounding like a noob (that is because I am).
I am building a wearable device as a hobby, and I need a 6-axis gyroscope with IMU. Ideally, the device should have more than one IMU, but considering that I have absolutely no idea how to even assemble the device, I am reaching out to this forum to hopefully get an initial idea of what it is I need, so as to hopefully set me off in the right path.
The sensors I am thinking in using: Initially I have been looking at ASM330LHHTR and A3G4250DTR, strictly because they are small. The idea I have is to begin testing with a simple setup connected to power, but to eventually make it battery-powered.
A bit more information about what I want to measure: eventually I want to set up a strip of these IMUs in a straight line, and have them measure at the same time, and feed it to something like a raspberry pi so as to transmit BT signal.
To make a setup where I have IMU --> [something] --> BT-Signal-Generator, I can obviously argue back and forth with AI, but I was hoping to get more specific assistance from anyone who may have used these kinds of sensors in the past and who may know exactly what I need for that [something] part. I understand I may need a multiplexer if I am using multiple IMUs (or do I?), to integrate the different IMU signals and discriminate each sensor.
Why am I even here asking for help: as I previously established, I have no idea how to do this, but I think I understand in theory what I need to do it. What I would like to know is the following:
1. Are there any extra/miscellaneous parts that I am not aware of, and that I should include in my setup to achieve my desired purpose? Specifically, whatever device/s should go into the [something] part (mentioned above)
2. Considering the setup mentioned, is there a better/more appropriate IMU/gyroscope that is recommended? If so, how would this change the setup in (1)?
Thank you very much for y'all's time.
