I am quite a newbie in MEMS sensors!
Just got a sensor Tile at hand, having fun with this device and the app.
I am wondering if someone uses 3D accelerometers like LIS3DH to measure the respiration rate(or breath rate)?
If I lay down with sensor on my chest, usually I have few hundreds of mg, like below: (using LSM6DSM on the sensor Tile board)
(I just noticed that the above x axis is sample counts, not time. Sorry about that!)
So it seems possible to use accelerometer ic to measure respiration rate!
Or is there any other MEMS sensor can be used to get respiration rate?
Thanks for reading this post!
