Two example programs that use the M4! command to return solar radiation (W/m^2), raw millivolt value (mV), sensor temperature (°C), and Z-axis values (°). The programs also calculate the daily total flux (MJ). One example program also controls the heater based on air temperature measurements, dewpoint calculations, and battery voltage measurements. The HygroVue™10 Air Temperature and Relative Humidity Probe provides the measurements used in the dewpoint calculation.
