I want to know if the above mentioned scenario is possible with adxl345? If you are saying no! then what would be the right sensor for the above application.
Just checking back in. It sounds like this might be interesting to explore with some trials. While the ADXL345 will not support long-term position tracking on its own, there might be some unique attributes in the responses that could be exposed with the right algorithms. I will assume that this is closed for now, but please let us know if you have more ideas/questions to offer on this topic.
Interesting question, but I am not sure we have enough information to answer it with confidence. The ADXL345 measures linear acceleration, not position. You can double integrate the ADXL345's measurements to estimate position displacement. Are you asking if the acceleration response associated with "moving a bag" will be different enough from the normal motion that an object will experience on a train?
