yes, but apparently only using accelerometer data, results in a lot of false positives. Many algorithm combine gyroscope data (and magnetometer too for orientation) to provide more secure outputs. I also would like to add some AI to the algorithm so i need a little computational abilities from the c...

Sorry guys, new to the topics, i red it but too many acronyms. So be patient please. As said i am trying the several solution i can use for assembling a accelerometer with a chip and a wifi module as well as a LiPo battery I set up a bundle with photon, the particle, IMU shield and battery shield.. ...

i'm massimo banzi ( not the Arduino one alas) and i'm interested in fall detection systems.
Would like to know what is the difference between the Photon IMU shield and the MPU-9250 9 axis MEMS
Thank You
