Need a little help with an engineering solution using an accelerometer and sensors...
Hi everyone, I'm new here and probably will frequently be using this forum. I ran into a small wall as far as this project I am working. Here it is...
I'm installing a display system into a vehicle. My job in particular is to design a solution that shuts down the display system when the vehicle is in motion. I would like to implement an accelerometer and vibration sensor interfaced with a typical embedded board like an arduino. I understand that when the vehicle begins accelerating, the accelerometer will catch this and I can use this data to shut down the system immediately. It is just when the vehicle reaches a constant speed that I am worried about. When it reaches a constant speed, almost no acceleration will be noticeable. I could implement a vibration sensor but sometimes vehicles can idle smoothly not giving off too much vibration.
Anyone have any other idea how I could approach this? Thanks
