Amazon Smart Air Quality Monitor doesn’t have a microphone or a speaker to sound an alarm, and Alexa isn’t built in. For voice control, alerts, and full Routines support use any Echo device (sold separately) or the Alexa mobile app.
This device is an air quality monitor capable of registering carbon monoxide (CO) levels. It is not a substitute for a carbon monoxide alarm, and is not certified as a CO alarm or detector. This device does not measure Carbon Dioxide (CO2) or Radon.

Amazon Smart Air Quality Monitor measures 5 important factors of air quality: particulate matter (PM 2.5), volatile organic compounds (VOCs), carbon monoxide (CO), humidity, and temperature.
This is a great addition to your smart home whether everyone is in good health or no so good. The power of knowing is having more control.
You can pick one up here. On Amazon.
