Register 0x1002 + 0x1003, Irradiance, provides the solar radiation output in 0.01 W/m².
The value given must be divided by 100 to get the value in W/m². MSW and LSW should
be read together in one request.
Register 0x1006, Instrument body temperature, provides the temperature of the
instrument body in 0.01 °C. The data must be divided by 100 to achieve the value in °C.
Register 0x1007, Sensor electrical resistance, sensor resistance in 0.1 Ω. The data needs
to be divided by 10 to get the value in Ω. This register returns a 0 by default. To read the
resistance, first a measurement has to be performed. This can be done by writing 0xFF00
to coil 2. Hukseflux recommends to use this function only when necessary for diagnostics
in case of sensor failure.
Register 0x1008, Scaling factor irradiance, default scaling factor is 100
