extend range for mfrc522 rfid reader I need it explained exactly what changes are needed and where to put them. If you're still looking for an answer, nielkun, try using: I had to replace both "mfrc522" with "rfid" in that line for it to compile. In this specific circumstance I am trying to write to the NFC to “get” a URL each time it’s tapped (using hooks to automate something via url retrieval). I’ve simply tested trying to read it through Shortcuts and NFC Tools since it won’t work normally.

i stumbled over this thread today while i played around with my new MFRC522 RFID Reader. My intention was, to be able to read the rfid-cards through my door. Therefore i wanted to extend the range of the reader. I had success by placing a . I am using the Addicore RFID library and have successfully set up a working sketch, now however I have come across a problem. The RFID reader can't read through the 3cm of wood I want it to read through, and I therefore try to increase the range of it. I need it explained exactly what changes are needed and where to put them. If you're still looking for an answer, nielkun, try using: I had to replace both "mfrc522" with "rfid" in that line for it to compile. Here are some things I've considered: Ditch the embedded antenna on the cheap RFID reader and construct my own, larger antenna. I'd need to see if the onboard MFRC522 is up to the task of providing additional power. Look for a .

The RC522 RC522 Reader Kit includes the RC522 RF522 RFID Module, RFID Card, RFID Key Fob, and a few male headers to solder. The RFID tags, i.e., RFID Card and RDIF Key Fob in this kit, are compatible with MIFARE 1K tags (each has 1 KB memory). In this guide, we'll explore how to use the MFRC522 RFID module with an Arduino. By the end of this article, you'll be able to create a simple RFID reader system and understand how RFID technology works. My current intent is to use an RFID reader module (possibly the MFRC522) connected to a microcontroller (I currently use a TM4C123GH6PM, but would switch to Arduino if it would be easier) to read in ~60 RFID tags stacked directly on top of each other.

I'm using the MFRC522 library, and the basic code is: mfrc522.PCD_Init(); mfrc522.PCD_SetAntennaGain(mfrc522.RxGain_max); But still the range is pretty shitty. I want to read the RFID tag thru my 4cm thick wooden door, but that won't work this way. You can get a much longer range with the lower frequency reader. That product has a read range of 180mm where as the 125KHz I designed has a range of 18 inches, and with a suitable coil could exceed 6 feet. The effective read range is limited by a combination of factors, like the strength of the reader field, size of the antenna, and the sensitivity of the reader receiver's detector. Unfortunately, these are highly resonant LC (inductor/capacitor) systems where changing one parameter will necessitate changing others to keep the system resonant.
