Hi
I have a project to control wheeled-robot by using head tilt, in four direction, I need to use accelerometer to do this job, i need very sensitive and accurate sensor to detect any change in head orientation. really i don't have good experience in accelerometer and which one should i use for this project, I am use EFM32 ARM microcontroller, can any one help me in the best choice for this project. digital or analog, 3 axis or less, with gyro and magnetometer or alone, with which sensitivity and accuracy rang.
Thank you very much for helping me

Re: Help in sensor selection
You can do tilt with a 3-axis accelerometer. For your application, something like this one would work: https://www.adafruit.com/products/2019
I'd use the lowest (2G) range for the best resolution.
Adding a magnetometer and Gyro would give you rotation as well as tilt. This Absolute Orientation IMU has all the hard sensor fusion math built in.
