Using Leaf Wetness Variables in Reports
Leaf wetness sensor outputs raw data that can be included in reports or
stored into log files. Additionally, MAWS Lizard creates an alarm
component that reports on/off information about leaf wetness.
To check which variables are available, proceed as follows:
1. Go to the Reports view.
2. Create a new report or select an existing one to include the
variables for the leaf wetness sensor.
3. Click LWMeasQLW102_1 and QLW102Wetness_1 in the
Available list box in the Select variables frame. Lizard displays
the items that are available for the source in question.
The LWMeasQLW102_1 variables are outlined in Table 6 on page 84 .
QLW102Wetness_1 has one variable: status, indicating whether the
leaf is wet or dry (1 = wet, 0 = dry). You can set the limit between wet
and dry in the Alarms view. The default value is 7 (based on the
LWMeasQLW102_1 measurement) and it can be changed in the Input
threshold for indication field.
