So I need to detect 2 objects within a 50>100cm range on a single axis and this needs to be done quickly, they need to have unique identification to trigger certain events. And ideally not require the sale of an organ like UhF RFID.. any ideas ?
Try to illustrate the physics of the items. Also tell the big picture, what the purpose is of this build.
A ball being thrown through a ring
Using different colours on the balls?
What would "quickly" look like in numbers?
So each ball needs to have a passive or active transmitter, when it is sent through the hoop i need a unique identifiable trigger so i can acticate different lights or what not, the balls will be fired from an air cannon so pretty quickly,
What's the point in doing this? What is the end target? What is "pretty quickly" in numbers? Try and search for "pretty quickly" sensors...
No because conventional RFID will not detect more than one object in the coil field. Only UHF readers can do this because they have a system of collision detection built into them that is not available on the lower frequency tags.
Note the word "organ" is being used in a way that makes no sense, in English. So I assume you are not a native speaker.
That is a rather bold assumption there my friend, and an incorrect one. its a little bit of humor based on the age old joke that i might have to sell an organ to afford the component needed, the grammatical error and muddling of the terminology is the joke.
Well I did spend a time designing RFID readers professionally, so I sort of know what is around and possible.
OK, well I am in the UK and you can't sell organs, it is illegal. So I am not very conversant with the phrase. Sorry.
UK website here, appears to sell organs;
No the assumtion was about me not being a native speaker, i meant no offence surrounding your knowledge on RFID, thats why i came to the forum to ask after all, and unfortunately text based jokes often lack the context of in person jokes.
If you have any knowledge you would be happy to share on a cost effective solution or a custom antena i would greatly apreciate it
