The Daytime Fan-Aspirated Shield Kit can be installed on any Vantage Pro2 or PLUS standard ISS model to provide even more accurate temperature and humidly readings.
The kit contains a solar-powered fan that draws outside air over the temperature and humidity sensors to reduce the effects of daytime radiation on temperature and humidity readings. The solar-powered fan runs during the day. Since there is no backup battery, the fan will cease running when night falls and the effects of the radiation are minimal.
