Is there any way to make a device to locate animals? Like an airtag but from unlimited distance? I mean, no way there is no way to make a small sized android device with a sim connected to internet that shares location right?

@@nellovx It is possible if you build a battery-powered device with SIM + GPS and a simple server with a static IP. But this is very cumbersome.

how many connections an anchor supports, from tags. for example, in a room there are 2 anchors and 100 tags, can each tag count the distance to the anchors?
@ThatProject

Interesting question. As far as I know, up to 16 anchors can be recognized in one tag. There is no mention of the number of tags, but I'll try to find them.

Hi Eric, have you tested the range of two ESPUWB devices instead of one with custom build? The range I’m getting is only about 10 meters… my setting is at MODE_LONGDATA_RANGE_LOWPOWER, which is what you have as well. Love your videos by the way!

That's correct. MODE_LONGDATA_RANGE_LOWPOWER allows communication over the longest distance. What device do you use?

Hey Paul, the UWB chip I used is the BU01, which is a cloned version of the DWM1000. If you want a better signal, use the DWM1000. Since this has a ceramic antenna, I think you can get much more reliable results.

@@321oen LoRa is only capable of long-distance communication, and cannot recognize close distances like UWB. Your question was whether UWB could cover a distance of 200 meters or so. And that's impossible. I think about 50 meters is the maximum distance where there are no obstacles. In another video, I tested X, Y, and Z with 4 anchors and 1 tag. kzitem.info/news/bejne/mKWbzqR4o6Kmloo

@@ThatProjectI have seen the video, it helped me to understand more, I have the same idea but with more range, do you think if it's possible to extend twice the range incrementing the number of anchors? 8 anchors instead of 4, like two grids or more if you need more distance, where the tags are the actors that move inside the grids and you get their exact position, I don't know if is possible, I'm just learning. Maybe the solution isn't complex but expensive. Btw, your channel is very interesting, I see you have unity videos, thanks for such a good content!

@@321oen That's a good question. I have an answer to your question. What we need to focus on is the anchor device, not the tag device. Place the Anchor devices about 50 meters apart to cover the incredibly large area you want. Then you can cover as much distance as you want. But this will increase the cost as you said. The library currently in use can communicate with multiple anchor devices in a single tag device, but not vice versa. If you can handle multiple tag devices on the anchor device, you can build a much better system. (I'm too busy to have time to do it.)

can this project still work while the anchor is dynamic position relative to the tag
@ThatProject
2 жыл бұрын
Even if the anchor and tag move dynamically, the distance between the two devices can be measured continuously because they measure relative. (UWB uses the time of flight instead of signal strength for distance measurements.)
