Keep the tag 2.5-4 cm from the antenna, and the reader can read data continuously. The Grove-125KHz RFID Reader is a module used to read EM4100 RFID card information with two output formats: Uart and Wiegand. It has a high sensitivity with a maximum 7cm sensing distance.
It has a sensitivity with maximum 7cm sensing distance. An RTC (Real-Time Clock) module keeps track of the current year, month, day as well as the time, using a single lithium cell even though there is no power to the circuit. Arduino based Home Security Project. [] Every module has one function, such as touch sensing, creating audio effect and so on. Technische Merkmale • 7 cm Abtastentfernung • 125kHz RFID - nur Kartenleser • Arduino Library • 2 Ausgabeformate wählbar: UART oder Wiegand.
Hence, users have to write their own software library.If this is the first time you work with Arduino, we firmly recommend you to see If we don't have Grove Base Shield, We also can directly connect Grove_Ultrasonic_Ranger to Seeeduino as below. RFID is useful to identify people, to make transactions, etc… You can use an RFID system to open a door. This Grove-125KHz RFID Reader is a module used to read uem4100 RFID card information with two output formats: Uart and Wiegand. Compatibility. The In Wiegand Mode, output data is formatted with 26bits including 24bits card info and 2 bits parity.A2: The RFID reader can read tags continuously without any setting. Beschreibung Beim Grove - 125KHz RFID Reader handelt es sich um ein Modul für das Lesen von uem4100 RFID Karteninformationen in zwei Ausgabeformaten: Uart und Wiegand. [] All rights reserved. link between the computer and the SoftSerial Shield SoftSerial Shield is connected to the Software UART:D2&D3// if date is coming from software serial port ==> data is coming from SoftSerial shield// if no data transmission ends, write buffer to hardware serial port// call clearBufferArray function to clear the stored data from the array// if data is available on hardware serial port ==> data is coming from PC or notebook And if the distance is below 2.5cm, the reader reads data once if not moving tags away. The project Arduino and RFID Based Attendance System With GSM is a simple and is used at any place where attendance is taken for maintainin.
