Looking for a method to measure distance. Need to measure the distance from 75 to about 600 feet. Thinking about using a couple sets of the cheap RF modules. Put a rec. and tran. together at each end. Send a very short burst of RF and have the R. trigger the T. direct. Then repeat at the other end in a continuous cycle. If I can get this to happen, I can then divide this pulses rate down to a reasonably easy time signal to process. One end will be stationary and the other end will be continuously moving. Hope this makes sense. — My question is what modules would work best. All I need is a fast response to turn on the RF for about 100 ns, and then have the far R to detect the signal and trigger its T. Anyone have suggestions on which modules you have used, or suggestions for me to try? Anyone have an alternative or simpler method for this project? Thanks.
The only commercial items we have would be lasers. Your approach seems sound, but we have nothing along those lines. We’re always on the lookout for sensors, so if we come across anything, we’ll do our best to carry it now that we know there’s demand.
