Description
[PERGAM_FALCON]
FREQUENCY_HZ
2
Measuring frequency, Hz. Available
values: 2 Hz, 1 Hz, or lower (see Note
under the table)
SERIAL_DEVICE
/dev/ttyUSB0
UART serial device. The built-in Pergam
Laser Falcon UART adapter is used.
Note: The Pergam Laser Falcon measures the methane concentration every 100ms, and a
series of 5 measurements are combined into an average. The average and intermediate
measurements are stored on the Pergam Laser Falcon board and can be sent upon request.
The stored information is updated every 500 ms. The FREQUENCY_HZ parameter only sets
the frequency of requests from SkyHub to the Pergam Laser Falcon, while the Pergam Laser
Falcon continues to work according to its scheme.
