Fatigue Sensor
1Introduction
1.1 About the Functionality
The fatigue sensor is a driver monitoring sensor, from which you can request real-time pictures
when driver fatigue/distraction is detected or on-demand via an SMS command. The pictures are
stored in the SD card of the tracking device or the internal sensor memory in a .jpg format. The user
can remotely manage these pictures.
This feature description applies to tracking devices with the latest firmware version.
You can get the newest firmware and configurator from our documentation website: doc.ruptela.lt

2Principles of Operation
2.1 Operation
Once the sensor detects a distracted or drowsy driver, it will immediately send out a sharp and loud
alarm. At the same time, the sensor’s camera will take a picture.
If the fatigue sensor is enabled in the configuration, it will send the gathered data (file name, source
ID and alert ID) to the tracking device. If requested, the tracking device will represent the gathered
data and can also indicate how many pictures were taken since the last record and were stored in
the SD card. If the tracking device has not obtained the correct date and time from GNSS fix, NTP
server, or GSM operator, pictures cannot be taken or sent to the server.
2.2 Picture Storage
If the tracking device has an SD card, the pictures will be stored in the card and sent to a server
upon request. If the fatigue sensor folder on the SD card is full, the oldest picture will be overwritten.
If the folder is full and there are no pictures on the card, the taken picture will be discarded. After
receiving the pictures, the server can then send a request to delete them from the SD card in order
to conserve the memory. A maximum of 2000 pictures can be stored in the fatigue sensor folder.
If there is no SD card in the tracking device, no pictures will be taken. The fatigue sensor will indicate
alerts in any case.
If you insert/remove the SD card, the tracking device should be restarted to ensure correct
operation.

5Picture Request via SMS
You can take pictures on-demand with the snapshot SMS command, using the following structure:
password snapshot 3
After sending the SMS command, the tracking device will send a response, using the following
structure: snapshot 3 <answer>
<answer> can be one of the following:
• ok –indicates that the fatigue sensor took a picture successfully;
• busy –indicates that the fatigue sensor is busy with a previously taken picture at the
moment;
• n/a –indicates that the fatigue sensor is either not configured, not connected or not
responding;
• fullsd –indicates that the memory of the SD card is full and the picture will be discarded, as
there are no pictures to be overwritten;
• err –indicates that there was an error.
If the SD card is missing and the SMS command snapshot is received, the device responds with
sdcard missing .
Example:
Request:
password snapshot 3
Response:
snapshot 3 ok
