RFID is frequency Identification. An RFID reader is employed to learn RFID tags (which comprise sure distinctive knowledge saved throughout a chip). An RFID reader and an RFID tag, each have a coil surrounding them.This contactless 3V-5V RFID YHY502CG Reader Author UART Interface module is supposed for a easy reader adaptation to a quantity to make use of this machine for take a look at and utility function. there’s want only one command to finish one motion, like learn or write card knowledge. It wants no request or choice. The module will roll within the hay for you mechanically. What you want to is solely ship one command to the module. Then it will remit what you want to . Something is just so easy then simple. Additionally, if there’s any card enter the rf discipline, the crimson led on the module will mild and due to this fact the SIG pin will change from “1” to “0” to level the occasion.
This HY502 sequence of RFID reader/author modules are supported non-contact card reader ASCI chip appropriate with ISO14443 commonplace. It makes use of 600nm CMOS EEPROM know-how, helps ISO14443 A protocol, and likewise helps the MIFARE commonplace encryption algorithm. The chipset integrates analogue modulation and demodulation circuits solely require minimal peripheral circuits to operate. The module helps UART interface. The digital circuits have twin working voltages mode, TTL and CMOS. The HY502 module is concentrating on water, electrical energy, gasoline meters, merchandising machines, entry management, elevators, ingesting fountains, phone billing system or different identification card reader system functions.
Customers can merely choose the required interfaces to reap the whole operation of the system and do not received to battle with the difficult radio base station design. HY502 sequence helps Mifare One S50, S70, Extremely Gentle & Mifare Professional, FM11RF08 and different appropriate playing cards. It are sometimes set to mechanically discover playing cards, by default, to mechanically discover playing cards. HY502 sequence are low-power modules, wide-voltage 2.7 ~ 5.5V, makes use of an built-in module with an embedded antenna and will considerably scale back PCB measurement.
When a excessive worth is shipped to the SEL pin of the reader, TTL Serial communication is enabled.
This HY502 sequence of RFID reader/author modules are supported non-contact card reader ASCI chip appropriate with ISO14443 commonplace. It makes use of 600nm CMOS EEPROM know-how, helps ISO14443 A protocol, and likewise helps the MIFARE commonplace encryption algorithm.
