![]() If the fingerprint was registered correctly, it will show the message “Fingerprint DOES match!”, followed by the position where it was saved and the message “Registered!” We save the first fingerprint in position 1 and then we give it enter and follow the instructions: We open the Arduino Serial Monitor to start recording the tracks and follow the instructions: What is inside in R307 fingerprint sensor Subsequently, the reading and comparison sequence can be started to verify the fingerprints of the users and thus be able to discern and execute actions based on the result. To be able to use the device, it is necessary to save the fingerprints in its database. -Working environment: -10 º c to 40 º c (Relative Humidity 40% to 85%).-Baud rate: 9600 * NN = 1 to 12 (Default is 6). ![]() The device’s LED lights up every time it is taking pictures for fingerprints. The device has the capacity to store up to 162 fingerprints in its internal FLASH memory. The device works with the serial protocol, so it can be used with any microcontroller (arduino etc.) or development card. The biometric fingerprint sensor is ideal to create a system capable of protecting what you require through the analysis of your fingerprint.
