125KHz RFID Reader distance

Products & Technology Grove
#1

Hello,



I’m using the component: http://wiki.seeedstudio.com/Grove-125KHz_RFID_Reader/

I have build a program using Python with raspberry zero to read the RFID tag number and everything is working fine. I was just wondering how I can boost the reading distance. Can I push up the input voltage? Can I set a parameter? Do I need to build a new antenna?

I would like a reading distance of 8 cm, but now I must push the badge against the antenna to get a read.

Thank you,



best regards,



Sander

Hi Sander,



You can change to 51*82 antenna to extend the ranger. But we do not sale the antenna separately. How many quantity do you need? thanks.
