@Ruslan's excellent answer to What it the outer part of the sun, that we see with our eyes, called? and its link to David R. Brooks' Photographing the Solar Aureole led me to Forest M. Mims III (2003) in Applied Optics 42, (3) 492 Solar Aureoles Caused by Dust, Smoke, and Haze (also researchgate) and the author's other pages
the latter of which mentions the RadioShack Sun & Sky Monitoring Station. Below is a GIF from that page.
Question: What did Forest S. Mims III's RadioShack Sun & Sky Monitoring Station do? What sensors did it have and how did it record data?
disclaimer: I have no affiliation to the product, which I believe is no longer available in any event.
The GIF http://www.forrestmims.org/images/210_Animation_Sun_Sky_at_White_Sands_DSCN1722.gif won't play more than once in my browser once I embed it here as https://i.stack.imgur.com/wv3YW.gif so here are the five individual images; I've enlarged and sharpened them.
