What are the colors and symbols on the Nafas map?

Some of you have probably noticed that our sensor is showing multiple colors. You might even have noticed the various symbols —squares, circles, and triangles— of the sensors in our map view. To avoid further confusion, we will explain the meaning of colors and symbols on our sensors.

Let’s learn the color first!

Circle

Circle sensors are used to measure PM2.5, temperature, air pressure, and humidity.

Rectangle

Rectangle sensors are used to measure PM1, PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), temperature, air pressure, and humidity. 

Triangle

Triangle sensors are used to measure everything that is measured by circle sensors and can measure the levels of nitrous dioxide (NO2) and ozone (O3).

 

Keep in mind that red means bad air quality and green means good air quality.

Now, you have understood what all these symbols mean! 

You can easily read them and know the air quality in your area.

Let's live a healthy life by starting to monitor your air quality with Nafas.
