I have a question about BNO055 sensor. This is a 9DOF Absolute Orientation sensor which can measure acceleration up to 16g's.
I'm building a model rocket which will reach approximately 18g's of force and I need to use a 9DOF sensor. I already worked with BNO055 so I know how to code and optimize it.As I know the rocket will exceed BNO055's operation range and I won't be able to sense acceleration. However I want to use other sensor data's such as gyroscope and magnetometer of BNO055.
Does that acceleration difference let me sense the data I want?
What happens if I use BNO055 + ADXL375 sensors?
Do I need to do extra work to get x,y,z angles of the rocket ?
Or is this a stupid thing to do, better way is to use 3 different sensors with different breakout boards?
I think you are asking if the other sensors in the package will continue to operate within their linear range even if the acceleration exceeds the 16g maximum quoted for the accelerometer? Unless anyone has direct knowledge, probably only Bosch could answer that.
An interesting experiment could be to set up a centrifuge and mount a complete sensor + arduino + bluetooth link + battery, spin it up, and see what you get. This website:
suggests that you wouldn't need to spin it impossibly fast (107rpm at 15cm) though you would have to make sure the mechanics were soundly built and balanced, and keep your fingers out of the way!

Yes this is exactly what I am asking.
Experiment idea is probably the way to go but I dont think I have that amount of time and money
I would see what the data sheet states for your particular sensor. Be sure to use the data sheet from the manufacturer of your sensor. Many times you will find a maximum operational point but another one that the sensor will survive. Example an IC is rated 0-70C and shipping is -40 to 115C. It will be accurate from 0-70 but beyond that no but if it is exposed to say 85C and not powered it will be OK. This is the best I can do without a data sheet on your sensor is. Links help this way.
