Is there an RFID chip that lets you add sensor input?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of integrating a sensor into an RFID circuit for a project. Participants explore the potential for modifying existing RFID tags or creating new ones, focusing on the specific application of a pressure sensor.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the possibility of hacking an existing RFID tag to add a sensor, or if it would require purchasing a specific IC chip for a new tag.
  • Another participant shares links to examples of DIY RFID tags, suggesting that building custom tags is feasible.
  • A question is raised regarding the type of sensor needed, specifically asking about the voltage and current requirements for the proposed pressure sensor.
  • One participant mentions finding temperature sensors on a linked site and asks if pressure sensors are also available there.
  • A later reply points out that a specific pressure sensor is not RFID-compatible, but shares information about a nano sensor that operates on very low power.

Areas of Agreement / Disagreement

Participants express varying levels of certainty regarding the integration of sensors with RFID technology. There is no consensus on whether existing tags can be modified or if new tags must be created, and the discussion remains open-ended with multiple viewpoints presented.

Contextual Notes

Participants have not settled on specific technical requirements or limitations regarding the integration of sensors with RFID technology, and there are unresolved questions about the compatibility of various sensors.

Hi,

I am working on a project where I will be building my own sensor and would like to have this in an RFID circuit. I am new to this so any info pointers would be much appreciated. Here is what I would like to do:

The receiver would send a signal to energise the circuit. Using this energy, my sensor would send data to the IC chip, the IC chip would then send this captured data back to the reader.

Would it be possible to hack an existing tag (e.g. https://www.buyapi.ca/product/rfid-tag/) and add my sensor to the circuit or would it involve making a tag by buying a certain IC? If so, do you have any ideas which chips would be most suitable.

Much appreciated for your help

What kind of sensor? What voltage and current does it need? Looks like there are systems on the market that you may be able to leverage...

Thanks a lot. It will be a pressure sensor. At this early stage I am flexible on voltages, just want to see what the options are.
 
With a quick skim, I did find temperature sensors at that site I linked. Did you see any pressure sensors offered by them?
 
I've dropped them an email to ask, I'll report back.
