It would be useful if headlines said "~$10", "sub $100", "sub $1000" et cetera, instead of vague terms like "low-cost".

$10: https://www.ikea.com/us/en/p/vindriktning-air-quality-sensor...

presumably not quite feature-comparable, but the article and website are rather absent in report what exactly the "flatburn" is detecting - sounds like "fine particulate" (PM2.5? PM10?) and NO2

$640: https://shop.air-q.com/air-Q-pro-air-analyser-14-sensors

Or if you're building yourself, $35: https://sensirion.com/products/catalog/SEN55

Both include NO sensors.

It looks like the device uses a I2C interface.
