CS125 Present Weather Sensor
22
Particle count
Range
Definition
0-7200 Value represented by an integer number of the current number of particle per minute.
(-99 indicates either an error or that the sensor has been powered less than one minute)
Intensity value
Range
Definition
0-100.0 Value represented by a single precision value of the last hours rainfall intensity in
millimetres (-99 indicates either an error or that the sensor has been powered up less
than minute)
SYNOP code
Range
Definition
See section 10.2 SYNOP weather code for the last minute as defined by the WMO code table 4680.
(-1 indicates either an error or that the sensor has been powered up less than a minute)
METAR code
Range
Definition
See section 10.3 METAR weather code for the last minute as defined by the WMO code table 4678.
External temperature
Range
Definition
-40.0 - +80.0°C External temperature in degrees Celsius
Relative humidity
Range
Definition
0 - 100 External relative humidity in %RH (-99 indicates either a fault or no CS215 T/RH
sensor is connected)
11.4 Example CS125 message outputs
Basic format (visibility only)
0 9 0 6682 M ABCD
SYNOP present weather partial format
4 9 0 60 6682 M 0 0 54 4.5 63 20.2 91 ABCD
METAR present weather full format
8 9 0 60 6682 M 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 54 4.5 63 +RA 20.2 91 ABCD
Where:
9 is the sensor id
60 is the message interval (60 seconds)
6682 is the visibility in metres
M is the visibility units (metres)
54 is particle count
4.5 is intensity (4.5 mm/hr)
63 is the SYNOP code (heavy rain)
+RA is the METAR code (heavy rain)
20.2 is the temperature (20.2 deg. C)
91 is the RH (91%)
ABCD is the checksum
