ADXL345 impact detection

Other Hardware Sensors
1

Hi,

I am thinking of using an ADXL345 accelerometer in a project to detect if my device has a heavy collision with a wall/ hard surface. I was wondering whether anyone knows a good library or source to be able to achieve this. I need to trigger other events on a big collision.

Thanks

The ADXL345 can measure up to 16G.
So if you hit something, it is out of the range.
An accelerometer with a range up to 200G would be better.

A good library is perhaps Adafruit code or i2devlib.

Thanks, I found a ADXL377. Are there any cheaper, Arduino friendly accelerometers out there? Cheers
