Continuous Measurements (aR0!)
A sensor that is able to continuously monitor the phenomena to be
measured, does not require a start measurement command (M!). The data
can be read directly with the R0! command.
WS425 uses this command when the sensor is set to work in SDI-12
submode B. The command retrieves averaged wind data and gust wind
data. The averaging time window is selectable between 3 and 3600
seconds.
The command is the following:
aR0!
where
a = The sensor address.
R0 = The send continuous measurements command.
! = Terminates the command.
