Hello guys, im trying to make a long range rfid reader that can read passive rfid tag for distance 20cm to 30cm, but i couldn't found. I'm planning to use an Arduino Uno for this purpose. But I'm not sure of what reader module should I use, please give me a reference for this project, what rfid reader should i buy and what rfid tag, and ofc not as expensive as the parking system, im so open to all the discussion even if i should buy from other country, thank you so much
What frequency is your passive RFID tag designed for? When you know that, your search results may improve.
Okay, after i search i will 35mm Thin White Disk with 125 kHz, please give me some advice
Seems you are in uncharted territory, so plan on experimenting and failing a lot of times. Learn the physics of what works and what fails and why.
