Note: on subsequent gas measurements the last temperature instead of 25 degree C will be used.
Nearly irrelevant because this happens to return value of _calc_heater_resistance(200):
ambient_temperature = 30 -> int(84.9119287004)
ambient_temperature = 25 -> int(84.9119068473)
ambient_temperature = 20 -> int(84.9118849941)
ambient_temperature = 10 -> int(84.9118412877)
According to the datasheet the resolution delivered by the sensor is better
than 1 degree Celsius, 1 Pascal, 1 percent relative humidity etc. The user
should have the possibility to get floating point precision and figure out
what the measurement accuracy allows given their settings.
