Davis AirLink™ Professional Air Quality Sensor - introductory offer

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 have a circa 2006 vantage pro 2 base station - will this integrate correctly i.e will it receive and display the readings?

    The Davis AirLink works independantly of the Davis console as sends data directly to WeatherLink.com via your home WiFi. The data is then displayed on the WeatherLink App on a phone or tablet or a computer web browser. So it will not cause any problems with your existing system.

  • Can you tell me how long the USB cable is ? Thanks

    The USB cable is 1.8m / 6 feet in length. We have added a selection of USB extension cables to our website for customers that require this to be a little longer.

  • Can this unit be powered by USB

    The power supply for this unit it a barrel connector for the product which then plugs into a USB power adapter at the other end, so it is already a USB powered device with a USB mains adapter supplied.

  • Does the unit come with the cover shown in the pictures for outside use?

    Yes, the outside cover and a mounting bracket are included for outside use and wall mounting.

  • Hello Do you need a power supply for outdoor use / wired or batteries? Thank you

    Yes, a mains power supply is required to connect the AirLink which is supplied with the unit.
