RFID Access Control Shield for μRFID/EM-18/ID-3LA


This RFID Access Control Shield transforms your Arduino to an access control device. This unit is compatible with RFID modules such as micro RFID, EM-18 and ID-3LA. It includes almost everything that an access control system requires. Onboard Relay driving circuitry helps your Arduino to control magnetic locks, solenoid valve etc. The 5V buzzer provided on board can be used for indicating the RFID card acceptance, say single beep for card acceptance and double beep for rejection. 

Relay pins are available on a 3-pin screw terminal (NO,NC,COM) along with a 2-pin screw terminal for powering the 12V relay. Three LEDs are provided on board; STS, RLY and PWR. PWR indicates the power while RLY indicates relay actuation. STS comes in direct connection with  an Arduino pin (D12) and it can be controlled in accordance with your Arduino sketch.
