bonsair

See the air around you.

bonsair is a network of small environmental sensors. Each one measures the air where it stands. Together they draw a live map of the air we share.

What it measures

Six channels, measured around the clock.

Particles, gases, heat, moisture and pressure: the conditions you breathe in every minute but never see.

  1. PM2.5

    Fine particulate matter

    8.1µg/m³

  2. PM10

    Coarse particulate matter

    14µg/m³

  3. TVOC

    Volatile organic compounds

    112ppb

  4. Temperature

    Ambient air

    22.4°C

  5. Humidity

    Relative humidity

    48% RH

  6. Pressure

    Barometric

    1013hPa

Values shown are sample readings for illustration.

How it works

From one reading to a shared picture.

  1. 1

    Sense

    A bonsair device samples the air around it, continuously, wherever it is placed.

  2. 2

    Connect

    Readings are sent securely to the bonsair platform.

  3. 3

    Explore

    Every reading lands on an interactive global map, next to everyone else's.

The network

Local readings. A global picture.

One sensor tells you about your street. Each new one fills in the air around it, and the picture sharpens with every device that comes online.
