Each channel have might be configured by setting the following fields:
Figure 4: Weather Station Sample Program
Input
Signal source for the channel, selected from the list depending on the device.
The drop-down list includes:
-
SDI-12
– digital sensors operating in compliance with SDI-12 standard (see
)
-
Internal analog
– measurement of the logger's internal parameters such as: voltage of the built-in battery,
voltage of the external power source, 5V and 12V auxiliary power
-
MODBUS RTU
– digital sensors operating in compliance with MODBUS RTU standard (see
)
-
Pulse Counter
– predefined pulse sensor necessary for operating a rain gauge (usually tipping bucket rain
gauges), with pulse output
-
External analog
– measurement of analogue values of voltage and currents from external sensors (see
)
-
Wind Gauge
– predefined pulse counter necessary for operating a classic mechanical anemometer – pulse
output only
-
Status
– predefined pulse sensor for handling logical signal sources 1/0
Name
The
Name
field includes the name of the given channel defined by the user up to 20 characters. The name might include
any string of ASCII characters.
Parameter
The
Parameter
field allows to select additional options related to a given input signal type. The example below shows a
drop-down list of available parameters for
Internal Battery
.
Cycle
The
Cycle
field allows to define the measurement interval for that particular channel. You can choose intervals ranging
from 1 minute to 24 hours from the drop-down menu. Measurements shall be taken with respect to 00.00 hour of the
logger's time (
midnight reference
) without the option of entering a time shift. The table below indicates midnight
reference of taking measurements based on time interval values:
