I can't read a specific TID sensor

Just as you use a Select command to activate the temperature calculation on the sensor, you can also use a Select command to choose a particular EPC and tell any others to ignore subsequent commands. The details involve the way the UHF RFID tags work, and the specifics of the reader you are using. Keep in mind that you should send both the temperature Select and the EPC Select at the beginning of the same inventory round.


The AZN3200 measures the temperature of the chip on the tag. The chip has a small thermal mass, and it generally heats or cools to the ambient temperature within seconds.


In terms of the time required to read the tag, this can depend on a lot of things, like the RFID reader used, the reader settings, the number of tags in the area, the distance between the reader and tags, and other factors. Generally speaking though, you can get a single temperature reading from a tag around 2-10 times per second.
