Hi, I'm trying to create 2 components such that one can tell the distance it is from the other over a limited range. The first component will essentially be fixed, while the other can and will move quite rapidly (up to approx 20cm in 0.1 seconds). The fixed component needs to know how far away the other one is.
My requirements are:
1) The detection range needs to be between 5cm and 200cm 2) I need accuracy within ~5cm 3) The moving component needs to be quite light and small (
Stick a three axis accellerometer in the moving thing, and have it stored in a holster which is a known distance/angle from the stationary point and use the holster as the datum.
Then, you can use whatever wireless comms method you like and either process accelerometer info in the moving component and send positional data, or send raw accelerometer data and calculate positional in the stationary component.
That sounds like an ideal solution - many thanks Kevin :-)
