Reading the air across Bali…

Every speck drifting on this screen is particulate matter — the air you actually breathe, made visible.

Report what you smell

Approximate only — rounded to ~1 km, computed in your browser, never stored. We read the air within 3 km of you.

Sensors meet residents

When the data and the residents tell the same story.

"They're burning at night to avoid the sanctions." — resident report, sent to our WhatsApp bot

Nobody saw a headline. One neighbour smelled smoke and sent a message. A low-cost sensor nearby felt the same thing — particulate matter climbing while the kampung slept. A measurement, and a human voice, pointing at the same moment.

A sensor measures. A neighbour testifies. Together, they become evidence.

What residents are reporting

The map, in their own words.

The whole island

One map. Every sensor, every report, breathing in real time.

Pinch into your own banjar. The colour is always the air — never the noise of how many people reported. Clean stays calm, even where the reports pile up.
