I am looking for something to put into a concrete mixture. I will attach it to a rock particle and throw it into the mix. I will then want to know where the particle is at say every second (or half second or two seconds). It needs to be wireless and the cheaper the better of course. I will want the x,y,z with respect to an origin.

I would appreciate it if anyone can help. Thank you.

 

What are you going to do? Make a smart bomb?
