Climate change is real. Taking action is the hard part.

Oo is a sensor connected to an app providing real-time, step-by-step air quality. Finally, a problem we can now see, monitor and react to intelligently.

Library - the ideal place to bring Oo wearables to the community

Libraries are one of the most trusted spaces and sources of information that any country has. We believe they can play an increasingly important role in connecting residents to information, especially surrounding air pollution in real time.

In libraries, the Oo wearable sensor is available to be borrowed by patrons. When a patron borrows it, straps it on and begins to traverse the city, Oo transmits data to the user’s phone via Bluetooth, and the user can see their own personal exposure in real-time on the Oo  app. Oo’s sister company,, shares (visually) the recorded air pollution on a virtual, shared public map that the library monitors.

The breakthrough approach for the Oo sensor is if a person is standing in close range to somebody carrying the sensor, he or she is able to see their personal exposure in real-time (on the app) without having the sensor themself.

Oo is a true economy-sharing device.

Protecting the weakest in our society with Oo wearables

Exposure to air pollution is associated with neuroinflammation in children and dogs, per a recent study conducted in Mexico City. Air pollution in global megacities is linked to a cognitive decline in children and our young people are now rising up globally to defend their rights to a healthy life, on a global stage. We must respond with concrete changes to our habits. If things are to change, the responsibility is in our hands (“you” and “I”) in conjunction with our collective society and institutions. Footprints matter, yours too!

This is why we have developed a pet and a stroller clip variation of the Oo sensor to bring about awareness and stimulate real, structural change.

We will be creating crowdsourcing campaigns to generate funds for these, and will be posting a link to campaigns once they are ready.
