- About the ADXL50 accelerometer's resoloution:
-
- Full scale is -50g to 50g so that's (about) 100g Full Scale (FS)
- FS output span 0.8 to 2.8 Volts
- Zero-g output 1.80 Volts
- Sensitivity 20 mV/g (Milivolts per g)
- Voltage Noise:
- At bandwidth = 0.3 kHz +/- 0.33 %FS (I think this is +/- 0.33g)
- At bandwidth = 1.0kHz +/- 0.6 %FS (I think this is +/- 0.6g)
-
- So I don't think the resolution is really great but I don't have a good
- idea of the accelerations you might want to measure.
