Davis AirLink™ Professional Air Quality Sensor 

The Invisible Dangers of Air Quality

The air inside and outside your home is invisible even when it is dangerous. Breathing polluted air can lead to serious health issues, especially in children and adults with respiratory and health issues.

Know What You Breathe

AirLink measures outside or inside air quality and uploads readings to WeatherLink in realtime. Users will know the quality of the air they breathe. This information is vital to anyone with an air-quality sensitive family member, as well as those in cities, some workplace environments and where fires are likely to happen. AirLink is, literally, a product for everyone who cares about what they breathe.

The sensors can be installed indoors or outdoors and up to three sensors can be connected to an existing Davis weather station, giving Davis customers a new way to enhance their product. But no station is needed: new customers can use it as a stand-alone sensor.

Outdoor air-quality data is shown on the WeatherLink map so you you can compare you location to others in the area.

Ask a Question
  • I'm using this outdoors but all the charts are headed "Inside Air Quality", "Inside Current AQI", "Inside Temp/Hum" ,"Inside Particulate Matter" and so on. How do I change that text from inside to Outside?

    With the WeaatherLink phone/tablet app click on the account icon, then the device in question.  After this click AirLink (Edit) and finally settings.

    The top setting will allow you to provide the correct placement information.

  • is an extra cover required for outdoor use and will it's readings be added to my Vantage Pro2 information on Weatherlink.

    An extra cover for outdoors is not required. The sensor pack sits under a 'hood' which is seen in the second product image with the Davis logo on it.

    Yes, the AirLink will be added as an additional device to your Vantage Pro2 if you login using the same credentials when setting up the product. You can ignore the section in the guide relating to creating a WeatherLink account as you already have one.
