Sniffer Bike

Get to know the air around you

About

The Sniffer Bike is a particulate matter sensor developed by SODAQ and Civity. It first started as a development project in collaboration with the Utrecht Province. With a rising environmental concern of air pollution (World Health Organization), we believe in the interest to help combat this pollution. The Sniffer Bike plays a collective role in collecting data about the air so that individuals and governments would be more well aware of the environment. As an open-source project, we encourage everyone to participate and be involved so that better insights can be derived that would benefit everyone.

LTE-M is the backbone of the Sniffer Bike. It is a type of connection that is similar to the ones on mobile phones but made specifically for a low-powered Internet of Things applications. It measures the air every ten seconds and sends the data to the Data Platform of Civity every minute. You can determine the fate of your own data as to how and to whom you want the data to be made available. The data can be presented in an interactive dashboard, which gives a lot of insight into the environment, bicycle routes and air quality.

As a kickstart to this project, we have given ten cyclists a Sniffer Bike to gather first-hand data within the Utrecht province. After two weeks, the Sniffer Bikes have covered over 3800 km and a large amount of data as shown in the results further below. 

  

What we measure

PM10 - Coarse dust particles

PM2.5 - fine particles

PM1.0 - Fine particles

volatile organic compound (voc)

Results

This is how the data platform of civity looks.

On the left image you can see the particle matter surrounding each zone. A light blue blocks means that there are few particles in the air and it’s less polluted. Whilst the red blocks signify a high concentration of particulate matter (such as a lot of dust) which make the zone more polluted. On the top corner, you can adjust the types of particulate matter (which are 2.5µm or 10µm). By scrolling in and out of the image you can notice the different zones and their concentration of particle matters.

The right image  shows the specific bike paths that the Sniffer Bike has gone through. It has all the details of the of the concentration of the particle matters (both 2.5µm or 10µm) throughout the path. On the top right corner, you can select the IMEI of your Sniffer Bike.

 

Want to be part of the journey?

The best part of this project is that you can build your own Sniffer Bike! We have set up a Hackster tutorial on how exactly you can make it, from the assembly of the hardware to configuring the data on to the platform. Then, you can monitor your own air quality!
