NOTE
For using Continuous measurement commands for all WXT530 series
parameters (wind, PTU, precipitation, and supervisor) the select the
respective protocol (
aXU,M=R ).
The M=S selection requires use of aM , aMC , aC , aCC + aD
commands, only the precipitation data can be retrieved continuously
(using
aR3 command).
where
a
= Device address
R = Start continuous measurement command:
x = The desired sensor to make the measurement:
1 = Wind
2 = Temperature, humidity, pressure
3 = Precipitation
5 = Supervisor
If x is left out, the query refers to the combined data
message used for requesting data from several
sensors with just one command.
! = Command terminator
where
a
= Device address
<data
fields> = The measured parameters in selected units, separated
with '+' marks (or '-' marks in case of negative
parameter values). The maximum number of
parameters to be measured with one request is 15.
