I have used the same Adafruit fingerprint r308 sensor and a solenoid to open the lock. should be connect to output pin and another input pin connect to touch detect pin. Cheap biometric fingerprint sensor, Buy Quality biometric fingerprint directly from China fingerprint reader scanner Suppliers: R308 Biometric Fingerprint Module. 8) In R308 module must be first read datasheet. I can easily open the solenoid straight from datasheet4u the Arduino ( with or without the relay) provided the fingerprint sensor datasheet4u is not connected. GROW R308 Optical Fingerprint. It have CE certificate. Hi I bought R308 and I datasheet4u don' t r308 know how to connect it to Arduino ( Mega). 7) call FingerPrint_ Init( r308 osPriorityLow) in your any task.
This sensor has 6 wires: 1 = Red 2 = Black 3 = Yellow 4 = White 5 = Green 6 = Blue. Fingerprint reader can conduct secondary development, can be embedded i. need a digital switch for power. R308 optical fingerprint module r308 r308 have USB and UART port. The fingerprint sensor works fine to datasheet4u switch on LEDs when the correct fingerprint is detected.
