Modules and RFID tags

Radio communication is a short range (RFID), is included in so many areas of our lives that indeed it would be difficult to even briefly describe najpraktyczniejsze devices that use it. Your success of this technology should be extremely simple implementation, niwelującej the need to use separate power sources for all devices. If for RFID modules require power, in the case of the tags to run just energy flowing through the field generated through the transmitter antenna. In this category you will find many ready-made solutions – such as modules , transceivers, and RFID tagsthat are present in various sizes and designs. Part of the products has the features such as the NFC reader.

Current without wires, that is the power "from the air" - RFID CHIP

Most importantly, the obvious advantage of RFID technology is the ability to work without separate power sources for both connected devices. Although, of course, some devices (e.g., cell) served by the RFID transmission having its own power supply, in the case of tags, the energy required to run small electronic equipment is transmitted through the same electromagnetic field, which provides reliable data transfer between two devices. In other words, the magnetic field through the antenna module (that is a special coil), causing causing the coil leave a small current, which is enough to run the system, analyze the signal from the transmitter and send a short reply back to the sender (often the message contains the identifier that approximately can be taken – is a unique sequence of characters assigned to a specific tag).

RFID CHIP standards, Standards...

The world of RFID devices many years ago was divided into two main groups, differing in the frequency and detection area. The first of them works on radio frequency is 125 kHz and the other is mainly for devices, contactless, that is, the limits, mostly for a few inches – works in the frequency band of several tens of times higher (13.56 MHz). Other frequency not only makes the differences in the design of the modules, RFID, but also in the size of the antenna itself – in the case of lower frequencies are slightly large antenna, although the shape (flat battery) remains the same. You should know that the popular RFID tags are available in different forms depending on the targeted application. To determine the major items are good self-adhesive "pill", while very small objects may be marked using tags kapsułkowych, reminiscent of the slightly increased grain of rice with a diameter of around 2 mm and a length of just over 12 mm.

Modules and RFID tags and NFC reader and in the range of Botland

In this category we have collected a number of practical modules and RFID in both the above-described standards. If you need a module for reading labels 13.56 MHz, we highly recommend the Adafruit PN532 module with integrated PCB antenna and less showing two rows goldpinów module SM130 Mifare UART interface and I2C. In the main application is perfect known and loved the layout RC522, which is the heart inexpensive and very easy to implement module ME138. To support tags 125 kHz we recommend miniature modules RFID ID-12LA company SparkFun and communication modules for series system the ID-2, ID-3, ID-12 and ID-20. In our offer you will find, of course, a rich selection of RFID tags in the form of trinkets, cards, or capsules.
