If the total pollution cloud value under radar coverage could be output as a circuit signal from the radar it could be used to switch off polluting machines and automate controlling the spread.

There you go! Updated the mod with the new feature. The numbers will get quiet high as it sums up each tile not just the chunks

Fantastic thank you! I have dreams of circuit connecting all the lamps in my base to glow red the more pollution is out of control, and sirens blaring when enemies are detected incoming.
