Accelerometer fall detection

Need Help With My Project

Your virtual pin handler would look like this:

BLYNK_WRITE(V0)
{
 if (param.asInt() ==1)
  {
    // your code in here to store current XYZ value
  }
  else
  {
    // your code in here to clear XYZ value 
  }
}

and you’d use a BlynkTimer to call a function which reads your accelerometer on a regular basis, compares the current value to the stored value, and alerts you if there is a significant difference in the readings.

Presumably you also want to disable alerts when you’re riding the bike, so you could use a flag variable to achieve that…
