    Accelerometer to get Position

    Sorry but we have no access to the rail, we are just inside one box, which is running on this rail.

    Accelerometer to get Position

    Thanks BobM3 and GregLocock. To your questions: 1. Yes we are sampling with 100 Hz. We may try to sample with 1000 Hz. The sampling period is usually 5 seconds. 2. the current movement we are looking into is running in just one axis. It is on a rail. 3. for testing purposes we can sense the...

    Accelerometer to get Position

    GPS solutions are not possible, as we need to measure a distance of 45 cm with 10 % accuracy. Displacement sensor i cant also use, as everthing should be tiny, work on battery and inside a box full of materials. So a chip solution is desirable.

    Accelerometer to get Position

    My customer wanted us to use an accelerometer to get the curve of the velocity over the position. We used a 3 axis sensor, with analog output. Here we used a 12 bit ADC. Now all the effort has been done, but we cant get the exact position of the movement, which is a movement in just one axis...
