FINGERPRINT SENSOR
COM-FP-R301T
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 |
|---|---|
| 5 V | 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 USB interface converter – Joy-ITitem for this. Therefore, we connect the fingerprint sensor to the
adapter as shown below..
| Fingerprint sensor | SBC-TTL |
|---|---|
| 5 V (Red) | 5 V |
| 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.
We use the SBC-TTL because the sensor is supplied by 5 V and TXD /RDX 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 theGitHub – bastianraschke/pyfingerprint: Python library for ZhianTec
fingerprint sensors (e.g. ZFM-20,
ZFM-60)library by Bastian
Raschke, released under the
pyfingerprint/LICENSE at Development · bastianraschke/pyfingerprint ·
GitHub,
to control the fingerprint sensor. To
install the library and all its dependencies, run the following commands:
sudo bash
wget -O –https://apt.pm-codeworks.de/pm-codeworks.de.gpg | apt-key add
–
wgethttps://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
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**
USAGE WITH ARDUINO
4.1 Connection
| Fingerprint sensor | SBC-TTL |
|---|---|
| 5 V (Red) | 5 V |
| GND (Black) | GND |
| TXD (Yellow) | Pin 2 |
| RXD (White) | Pin 3 |
| Touch (Green) | – |
| 3,3 V (Blue) | – |
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 then only able to detect whether a finger has been placed on it via the touch pin and cannot read the fingerprint.
4.2 Installation
We use the library GitHub – adafruit/Adafruit-Fingerprint-Sensor-Library:
Arduino library for interfacing to the fingerprint sensor in the Adafruit
shop from
Adafruit Industries · GitHub, which is released
under the Adafruit-Fingerprint-Sensor-Library/license.txt at master ·
adafruit/Adafruit-Fingerprint-Sensor-Library ·
GitHub. 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.
