I am trying to do a project based on an idea I got, and I would love if you guys could tell me if its feasible and some tips and guide on what to do, and what arduino/cabels/other hardware I should buy.
I want to use 2 IMU sensors, I bought this one from Adafruit: Overview | Adafruit BNO055 Absolute Orientation Sensor | Adafruit Learning System
I want to attach one above the knee and the other below the knee, and send their data to a mini-controller (arduino?). like in this youtube video Knee angle measurement using a wireless body sensor network - YouTube but my technology will be different (I think he measure the distance between his sensors)
I want to know the angle between the knee all the time, 100hz of data will be pretty good
After I got this, I want to store the data on a database, I was thinking to send the data from the controller to an android app(via bluetooth or wi-fi?) and from there to store it to a database (what databse should I use?)
Do you think this idea is even feasible?
if yes, I would love to get some ideas on how to do it, what hardware to buy, what I need to learn and etc
