    HTRC110 long range RFID Reader

    Hi everyone, I am working on an RFID reader using HTRC110 with a coil antenna of 18cmx12cm but I could not get the desired range (at least 10cm) for a small tag 10*12mm like this one Hitag S 256 Pigeon Ring. In this document HTRC110 Application note I found out that I can use external power...
  3. Question about wire antenna design for 915HMz RFID EEPROM chip

    So I'm doing a quick proof of concept demo for work that uses these RFID chips. I'd like to make more of the demo units but I am out of the sticker tag antennas I use and I can't get more in time. I have the SL3S4021 model with two frontends. For my demo I want them to read from as far away as...

    Pet Microchip scan

    Hey Guys, So I'm pretty much a total noob how radio frequencies work. I stumbled on this forum and thought its a good place to ask this. Is there a way to build a large-distance animal microchip scanner? I was curious if there was a way to look for microchipped animals via scanning microchips in...
  5. simplest rf id

    hello, I hope to make a simple rfid that can transmit 20 different frequencies and receiver that can decode those signal transmitted from rfid. I hope that rfid without any transistor so i can design it very small I don't need it long range. I hope max 10 meter range. please post your Idea

    Detect 'FRIENDLY' and 'ALIEN' moving object

    Greetings Everyone. I am looking to develop a small educational project as an end of term project for my Graduate programme. The concept is to identify a moving object and then categorise it as either 'FRIENDLY' or 'ALIEN'. The term 'FRIENDLY' means they will be known to the system and the...

    Can't get MFRC522 (RFID) to work with PIC18F452 and SPI bus

    I don't know where to ask but I was wondering if someone here has worked with it and could give some idea. Hope so. A module ( MFRC522 ): Schematic: An MCU ( PIC18F452 ) is powered with 5V, module is powered from 5V(DC) -> 3.3V(DC) converter and all logic pins ( SS(SDA), SCK, MOSI, MISO...

    How can I connect my circuit to power?

    I am trying to build an escape room puzzle, where someone holds a key fob up to a sensor and a maglock opens, and I went online to buy something that I assumed was ready-in-box but instead they sent me the photo attached which I'm 99% sure was originally a car immobilizer and is now being used...

    How to read RFID tag by ATmega32 using Codevision ?

    Hey there, I wanna know how to write a code by Codevision for reading RF01D data... I know I should use USART...that's all I know... It's an ATmega 32 and RF01D in first step what changes should I apply on Codewizard? thanks
