An accelerometer measures movement.
A BCG sensor measures cardiac contractions, respiratory rate, and HRV.
These are not the same sensor. They do not produce the same data. And the buyer who purchases a device built on one while expecting the output of the other will tell you about it in their review.
"AI pet health monitor" now covers smart collars, visual scan apps, and GPS trackers — three categories with different hardware, different signals, and different buyers.
