Altruist in Thailand: a photo set
An air quality sensor spends its life in public, at head height, in weather. This is what that looks like: twenty-one frames of Altruist in Bangkok and on Koh Phangan, in the places whose air it measures.
No numbers in this post. We took a box of Altruists to Thailand and photographed them where they actually live — on columns and kerbs in Bangkok, on a scooter handlebar in the rain, on a white wall above the jungle on Koh Phangan.
At street level
A sensor is only honest about the air where it hangs. Ours spend their working life at roughly head height on a street: beside a traffic lane, under the skytrain, next to the awning you wait out a downpour under. That is the air in these frames — Sukhumvit, at the height where people breathe it.






The hat is not decoration
The cone on top is the first thing anyone asks about, and the answer is dull: tropical rain arrives sideways. The roof keeps the water off while leaving the air path open the whole way round. It has a second effect nobody planned for — the device reads as an object rather than as equipment. A small painted house on a pillar, which is roughly what it is.





After dark
Colour turns out to be the other half of the design. A grey box on a wall is infrastructure and nobody looks at it twice. A magenta one under shop lights gets asked about, and being asked about is how a citizen network grows.




And off the street
It does not have to be on a wall. A cube on a desk beside the map it feeds, a yellow one riding a scooter handlebar in the wet, a pink one on a white wall with the jungle filling the window.






Bangkok is on the map now — you can open it here.
The island in the last frames has been reporting for a year. That story, with the whole archive behind it, is in Koh Phangan, one year on.
