FINGERPRINT SENSOR COM-FP-R301T 1. GENERAL INFORMATION Dear customer, thank you for choosing our product. In the following, we will show you how to use this device. Should you encounter any unexpected problems during use, please do not hesitate to contact us.
. PINOUT Name Colour 5V Red GND Black TXD Yellow RXD White Touch Green 3,3 V Blue
. USAGE WITH RASPBERRY PI 3.1 Connection For the Raspberry Pi, we use a USB to TTL module. In our application example, we use our SBC-TTLitem for this. Therefore, we connect the fingerprint sensor to the adapter as shown below.. Fingerprint sensor SBC-TTL 5 V (Red) 5V GND (Black) GND TXD (Yellow) RXD RXD (White) TXD Touch (Green) - 3,3 V (Blue) - Now connect the SBC-TTL to one of your Raspberry Pi's USB ports.
3.3 Usage with the library If you now execute the following command, you can store a fingerprint. python3 /usr/share/doc/python3-fingerprint/examples/example_enroll.py You can use the following command to query your fingerprint to see if it is found in your data. python3 /usr/share/doc/python3-fingerprint/examples/example_search.py You can see how many fingerprints are currently stored by using the following command to see: python3 /usr/share/doc/python3-fingerprint/examples/example_index.py 4.
4.2 Installation We use the library Adafruit-Fingerprint-Sensor-Library from Adafruit, which is released under the BSD License. You can install the library in the Arduino IDE under Tools → Manage Libraries… . 4.3 Usage with the library You can run sample codes under File → Examples → Adafruit Fingerprint Sensor Library . You can use the enroll script to add fingerprints and fingerprint to compare a fingerprint to the stored data.
