The rocket maximum acceleration is 250m/s^2. I hesitate between choosing :
• ADXL377 3axis +- 200g (since the rocket's maximum acceleration is 250m/s^2, the resolution of this accelerometer worries me)
• ADXL78 one axis +-50g with H3LIS331DL 3axis +-100g (the ADXL technology is the most suitable for rocket so using one axis ADXL can be a bad idea).
Note : The accelerometer will be used to detect the apogee using kalman filter.
