What you'll do

A CO2 / VOC / particulate monitor that Claude Code built — an ESP32 reading three low-voltage sensors and a small trend analyzer that learns each room's normal air, watches the rate-of-rise, and pushes you a plain-English "open a window in the bedroom, CO2 is climbing" instead of a wall of raw numbers you'll ignore.
