HT30 WBGT calculations:
WBGT = Wet bulb Globe temperature
WB = Wet bulb temperature (Calculated from temperature and Humidity)
TG = Globe temperature
TA = Air temperature
OUT of the Sun (Indoors)
WBGT = 0.7xWB + 0.3xTG
IN full Sun (Outdoors)
WBGT = 0.7xWB + 0.2xTG + 0.1xTA
Sensor - Wet bulb calculator (sea level pressure)
