Hi all
I am currently working on a project for an electrical device but my knowledge of circuitry is very limited. I have done some research online and I think I’m on the right lines but would really appreciate some guidance if at all possible please.
The complete unit needs to be as small as possible. So far I am unsure exactly what I need and how small the components can be, how much power they would require and how much it would then weigh, so I guess any advice to answer these questions would be great.
Initially I believe I need an IMU that can measure very small movement up to around an inch. The movement would include pitch, roll & yaw. I then need to instantaneously transmit the data via Bluetooth. As far as I can work out I would need a Microprocessor but I may be wrong.
I am also thinking that the unit would need to have something included that would activate the device or at least the Bluetooth transmission. I was either thinking a hall effect sensor or perhaps activation via a very sensitive pressure switch.
I've been looking at the Sparkfun 6 degrees of freedom but this seems too big. Also the Arduino Pro Mini, Sparkfun BLU Mate 2 and the Sparkfun US1881 Hall Effect Sensor. Like I mentioned, I'm not sure exactly what components I need and it all needs to be really small. Basically, I'm a bit stuck.
Any advice would be really appreciated. Thanks in advance.
