Grove 125 kHz RFID Reader
Including €0.01 for ecotax
Presentation of the Grove 125 kHz RFID Reader
This is quite simply a Grove module capable of reading the information contained in a uem4100 RFID tag. This low-frequency reader has two information output formats: Wiegand (a very common interface format in this type of reader) and UART.
The reader’s range requires you to maintain a distance of 7 cm or less between the RFID badge reader and the uem4100 card. The Grove SEN11425P reader can be connected to a Base Shield or to the Arduino Mega Board Base Shield by means of a 4-core cable.
Applications for the low-frequency Grove 125 kHz RFID Reader
RFID technology opens up a great many opportunities: frequently used today in the world of industry and commerce, an RFID reader can also be built for educational projects or for home-made or experimental objects.
Reading the Grove 125 kHz RFID Reader data
Some possibilities include creating a system for opening a door controlled by RFID badge reading, creating a system for identifying an object or garment carrying a flexible or rigid RFID tag to create an anti-theft system – or even creating an interactive business card carrying information about its owner.
