Near field? Looking to measure withIn about a square foot in a tag rich environment. Want to only log the item or items with the given space and not the nearby items that could be above, below or next to the intended measurement space. More than one item might be correctly logged. Maybe smart shelf antenna? Outdoor antenna, some IP rating probably appreciated. Tags should be small, lightweight and passively powered by the antenna. Recommendations or pointers?

l0gic23 - It's definitely possible - you would need a proximity antenna as well as a tag with a shorter read distance as well. If it's on a shelf, you can definitely use a shelf antenna, if not, a proximity antenna would still work depending on your application. The only issue is that proximity antennas are generally rated for indoor environments. Here's a list of our proximity antennas - www.atlasrfidstore.com/proximity-rfid-antennas/ I don't know much about your application, but this Times-7 A1001 Proximity Antenna is a pretty good option because its near field and rated IP65 - www.atlasrfidstore.com/times-7-a1001-proximity-cp-indoor-rfid-antenna-global/ If you are looking for a shelf antenna, I like this Vulcan option that can be a near field or wide range antenna, depending on its settings, and has an IP rating of 64 - www.atlasrfidstore.com/vulcan-rfid-cp11-uhf-rfid-antenna-fcc-etsi/ As far as tags goes, all Passive UHF RFID tags will be passively powered by the antenna, but choosing an RFID tag for your application involves a lot of factors and information. The tag needs to work for the item you are tagging, and a lot of testing is recommended to find the perfect tag.

Hi Steven, I would like to use uhf rfid reader for school bus. with passive rfid tags whats your suggestion regarding that.
@atlasrfidstore3 жыл бұрын
Manshad, That completely depends on what the problem that you are trying to solve is. If you are looking to ensure that all students get on the school bus, then perhaps a fixed reader/antenna at the bus doorway can be used to read RFID tags on student's backpacks. If you just want to know what students have passed the reader/antenna system and how many times they have passed the reader/antenna system, then a fixed reader in the doorway would work like this Impinj R220 with two RFID antennas (www.atlasrfidstore.com/impinj-speedway-revolution-r220-uhf-rfid-reader-2-port/). However, if you wanted to read the RFID tags at all times when students were on the bus, you need to go with something more like the Impinj xArray on the bus ceiling. Here is the Impinj xArray - (www.atlasrfidstore.com/impinj-xarray-gateway-rfid-reader/) it is pretty expensive and should only be used if you need to read all tagged persons on the bus at all times. Powering either of these readers, however, will be difficult and something to think about before committing to using RFID technology as the solution. Do you have a solution for powering this system? Thanks!

Hello sir, I need a passive UHF RFID tag for moisture sensing applications using textiles. Could you please suggest to me which would be suitable with a read range of 7-9 meters?
@atlasrfidstore2 жыл бұрын
Madhu, There are only a few RFID tags on the market that do moisture sensing, i've copied the links below for the two moisture sensing tags tags that look like they are capable of your required read range. www.atlasrfidstore.com/smartrac-sensor-dogbone-rfid-rfmicron-magnus-s/ www.atlasrfidstore.com/smartrac-sensor-patch-rfid-wet-inlay-rfmicron-magnus-s2/ On their data sheets, it looks like they can get a read range of between 7-9 meters like you asked, but thats always subject to testing. Let me know if you have any other questions!

Hi sir I need for institute purpose for student attendance So is this is better to.install or some other system
@atlasrfidstore3 жыл бұрын
Jyoti, I think student attendance is a good use for RFID technology depending on exactly what you wanted from a system. For instance, if you would like to just read a student's tag as they come through the doorway, a fixed reader/antenna system can be setup at the doorway that could do just that. If you have more than 1 or 2 doorways however, it could start to get complicated. If you were looking at something for just one doorway, it could look similar to this: www.atlasrfidstore.com/impinj-speedway-xportal-gateway-rfid-reader/ Or you could make your own with just an RFID reader & RFID antenna like with this development kit. Keep in mind, this would not be as visually pleasing because you do not purchase the white plastic portal box. www.atlasrfidstore.com/impinj-speedway-revolution-r420-uhf-rfid-reader-evaluation-kit-4-port/ If you needed to constantly read all the tags in the room, for instance, read student A's RFID tag as long as the student is in the classroom, that could be a little more expensive. For that, i would recommend one or two of these, depending on the size of the classroom: www.atlasrfidstore.com/impinj-xarray-gateway-rfid-reader/ What other technology are you thinking about for this problem?

Hey Steven, What's your main applications for the RFID?
@atlasrfidstore4 жыл бұрын
Wendy, the applications we see most often for UHF RFID are asset management, inventory tracking, race timing, and access control. Any application where it is important to identify one item from another and possibly keep data on that item is where UHF RFID excels! Here is a good blog post on popular RFID applications for you to check out - www.atlasrfidstore.com/rfid-insider/what-is-rfid-used-for-in-applications/
