Getting Data Messages
You can get data messages with the aR4 command.
An example response:
0R4,Sr=0.5V,Ra=0.0M,Tr=13.2C,Sl=0.0V
You can set the gain for Sr and Sl.
Aux.rain Sensor Settings [aIA]
Gain [G]
[G] defines the pulses per rain unit, for example in mm.
If the Aux sensor has 10 pulses per a millimeter of rain and the user sets
the gain to 1/10, the transmitter reports the rain value in mm.
The range: 0.000 000 001 ... 1 000 000
For example, you can set aux rain gain for Young Model 52202/52203
Tipping Bucket Rain Gauge. The resolution is 0.1 mm per tip. Set the
gain to 0.1 * 2 = 0.2 so that the Ra rain amount WXT reports is in
millimeters. The multiplier 2 means that the tipping bucket sends one
pulse per two tips.
Sr Solar radiation (V = volts at input * gain)
Ra aux rain accumulation (M = mm)
Tr pt1000 (C = Celsius, F = Fahrenheit)
Sl Snow level (V = volts at input * gain)
