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.

3. 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..

Now connect the SBC-TTL to one of your Raspberry Pi's USB ports.
We use the SBC-TTL because the sensor is supplied by 5 V and TXD /RXD
only have a logic level of 3,3 V. Therefore, the Raspberry Pi could be
damaged during a direct connection with the sensor.
The pin Touch is an output pin, which sends a signal, if a finger has been
placed on the sensor. The sensor can be operated with the 3.3 V pin, but
is then only able to detect whether a finger has been placed on it via the
touch pin and cannot read the fingerprint.

3.2 Installation

We use the pyfingerprint library by bastianraschke, released under the

German Free Soware License

, to control the fingerprint sensor. To

install the library and all its dependencies, run the following commands:

wget -O - https://apt.pm-codeworks.de/pm-codeworks.de.gpg | apt-key add -

wget https://apt.pm-codeworks.de/pm-codeworks.list -P /etc/apt/sources.list.d/

apt-get update

apt-get install python3-fingerprint --yes

apt-get -f install

exit

sudo stty -F /dev/ttyAMA0 57600

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

The pin Touch is an output pin, which sends a signal, if a finger has been
placed on the sensor. The sensor can be operated with the 3.3 V pin, but
is then only able to detect whether a finger has been placed on it via the
touch pin and cannot read the fingerprint.

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

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.
When executing this, make sure that you have selected the correct Board
and Port in

Tools

.
