Simple RFID reading circuit, and simple RFID code ...

metraTec 17 nov. 2011 10:37 ( en réponse à Franklin_VTISL )

The few HF readers that I know that can read at 1m (I would say that there are 5 different ones worldwide that can do this) use Helmholtz antenna configurations with a diameter of around 70cm (this is physically limited), hand-picked large tags and readers the size of shoe boxes. Price for such readers is definitely above 1kEUR,...

How to setup a Raspberry Pi RFID RC522 Chip - Pi My Life Up

Ethernet Network Connection or Wifi dongle (The Pi 3 has WiFi inbuilt)

Assembling the RFID RC522

One thing you will notice when purchasing an RFID RC522 Reader is that 90% of them don't come with the header pins already soldered in. This means you will have to do it yourself, luckily soldering header pins is a rather simple task, even for beginners.

1. First off if the header pins you received...

Select the Right Oscilloscope Probe for Your Application ...

An oscilloscope probe is a fundamental part of an analog measurement system. Without an appropriate probe the best oscilloscope is useless. For that reason it is essential to choose the right probe to connect the circuit under test to your oscilloscope. Before choosing a probe, it is important to understand how probes work and how they are specified. Attenuation ratio, bandwidth, impedance, and...

What is RFID - How Does RFID Work

What is RFID?

RFID is an acronym for "radio-frequency identification" and refers to a technology whereby digital data encoded in RFID tags or smart labels (defined below) are captured by a reader via radio waves. RFID is similar to barcoding in that data from a tag or label are captured by a device that stores the data in a database. RFID, however, has several...

RFID Project Ideas For Engineers | Full Circuits With ...

Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to RFID reader for identification purposes. The tags do not require battery power. They derive power from the electromagnetic field generated from the reader. Some tags are also available which have their own power source. When it comes to RFID project...
