Grove - 125KHz RFID Reader output
Seeed 113020002 Grove - 125KHz RFID Reader UART or Wiegand Outputs The Grove 125KHz RFID Reader by Seeed gives two outputs. I am using this unit to create a RFID switch by using a relay to on/off a motor contactor. When I present the tag i get a 1 second pulse of approx 0.2v, measured across the output wires white and yellow. Can this be used to operate a relay which needs to keep motor running till power is removed. Then when power restored it will switch on so long as the tag is in range. Can i have some help on this please
