I'm undertaking a new project and I appreciate your help greatly as I lack knowledge with RFIDs...
I have a nano-scale "temperature" sensor (film) that sends a DC signal of it's current temperature... I would like to utilize RFID to send such signals to a computer.. below some requirements:
on the sensor side, only a RFID tag should store the current temperature and send its value when in range with a reader. minimal circuitry at this end is a mandatory..
an arduino hooked up to a reader periodically could scan for the temperature and stores it to a memory...
it has to be long range (1-3 meters)
the biggest challenge is to minimize circuitry at the sensor side..
No your biggest challenge is the range.
You will not be able to do this with a conventional tag. You will have to in effect build an active tag, that is one that is powered. It will need to contain a processor of some sorts.
Hi,
I not fully up with the latest RFID.
But how are you going to get the temp sensor to input to the RFID and get the RFID to transmit this info?
I don't see any input terminals on a shop security tag or my eftpos wavy thingy card, let alone a battery to run it.

I needed a suggestion from the RFID experts out there. all I have as of now a DC signal coming out of my temp sensor.. after that point, all is open for innovation
let's start with the question? is there any RFID tag that I can write sensor readings to that's compatible with Arduino. let's ignore the range for now..
Basically to write data to an RFID tag you need an Arduino system. So I can't see the point of doing so unless you then need to transfere it to another system. You might be better off using an SD card with built in Wi-Fi.
I assume that to get the DC out of your sensor you have to have some sort of power that you put in.
