Amazon unveils Alexa-enabled air quality sensor

Amazon has unveiled an Alexa-enabled air quality sensor. The $70 monitor alerts you to a range of harmful allergens and dust in your home. It can also pick up on the presence of carbon dioxide, and has built-in temperature and humidity controls.

If Alexa detects poor air quality, you can get notifications on your phone or even announcements on Echo devices.

Amazon Smart Air Quality Monitor doesn't have a speaker or microphone, and Alexa isn't built in. For voice control, use a compatible Alexa-enabled device, like an Echo (sold separately), or the Alexa app.
