Will sensitivity level affect 0g detection in accelerometers?
Both have a digital output pin that goes high when all three axes detect 0g, a freefall situation. I am planning to use this to activate my parachute deployment.
The maximum acceleration for water rockets is around 16 Gs, but since I'm not exactly measuring the data, I don't think the scale will be very important.
Which sensitivity level should I go with to offer the best chance for detecting freefall?
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

It would be more likely to survive continued use, and if you did decide to log and analyze, it would give a better analysis of your initial thrust and acceleration. They would both likely detect freefall equally, but the 3g/11g would deploy at 3g instead of 0, since that would be it's minimum range (unless the datasheet says otherwise)
Or you could use both.
