SODAQ AIR: portable air quality monitor

SODAQ AIR: portable air quality monitor

“Making the crowd aware of the immense changes in air quality in their daily lives and routines is where change can start to take place.”


Developing a portable air quality monitor to measure the levels of particulate matter in the air.

An air quality sensor that gives real-time, location-specific data about the air you’re breathing.

How does the AIR work?

The SODAQ AIR measures:

  • PM2.5 (particulate matter)
  • Indicative values for PM1.0, PM4.0, and PM10
  • Temperature
  • Humidity
  • Shock
  • Barometric pressure
Air quality monitor

The SODAQ AIR functions as both a static and portable air quality monitor that measures air quality in 10-second intervals. The LED strip on the AIR turns green, yellow, or red, to provide real-time insights into the air quality. All the air quality data is automatically sent to the global Knowyourair map, where it can be downloaded.  Read more about AIR.

The engineering process

The first rendition of the AIR proved to be quite a challenging process, as the technology required hadn’t yet been created. Our in-house expertise allowed us to create hardware small enough to mount on a bicycle, while still providing accurate data on air pollution. Over the years we’ve continued to decrease the AIRs dimensions, and increase its sensitivity while optimizing the device for low energy consumption. The current rendition of the AIR is powered by a supercapacitor which considerably increases the device’s lifetime.

The collaboration

In 2015, we created the first rendition of our portable air quality monitor. Then, in 2017, as part of a collaboration with the Dutch  Province of Utrecht and company Civity, the AIR became part of the Sniffer Bike project. This collaborative project came to its completion in January 2021, at which point the Dutch National Institute for Public Health and Environment (RIVM) examined the data and determined that, going forward, the portable air quality monitors would be valuable additions to the existing network of fixed air monitoring stations. In 2021 we made the AIR an off-the-shelf product and created the Know Your Air map to give individuals as well as smart cities and large companies access to an open-source database of global air quality measurements.

Closed Loop Management

Reduce risk and loss and boost supply chain performance with real-time visibility. Integrate the SODAQ TRACK Stealth into reusable small containers and boxes moving through your closed loop supply chain, providing you with control over moving assets.

For who?

Organizations with closed-loop supply chains looking to increase transparency and streamline the flow of assets throughout both their own and customer facilities.

  • Create a connected, transparent supply chain that delivers real-time visibility at every stage.

  • Receive location, motion or temperature threshold alerts, revealing the exact time and location.

  • Receive powerful data that enables you to make smarter supply chain decisions. With more control, you can minimize loss and waste, protect content integrity and reduce costs.

Using the TRACK Stealth allows you to monitor the temperature, motion and location of reusable supply chain assets. The Stealth is powered by a rechargeable supercapacitor which allows for an endless number of charging cycles and is able to power the device for up to 3 months.
