Air Quality affects your health.
Look after the air you breathe! 

Earn rewards and help us build a global air quality monitoring network to detect pollution hotspots and protect everyone’s health.

Why PlanetWatch

Air pollution kills seven million people every year worldwide. Because there are too few air quality sensors on the ground, many dangerous pollution hotspots are not detected. By deploying more sensors we will be able to better understand pollution dynamics and suggest more effective mitigation measures.


Do you know that air pollution has many potential sources and impacts people’s health in different ways depending on pollutants?


Connect your air quality sensor to PlanetWatch to help detect pollution hotspots and earn tokens in return for sensor data.

Stay Safe

PlanetWatch will help you avoid pollution hotspots when jogging or biking and keep a good air quality in your home.


We need a dense mesh of sensors to quickly detect problem areas. Our network blends consumer-grade devices together with more expensive systems managed by PlanetWatch. Consumer sensors are small, easy to install and remotely monitored.
