Amazon has introduced its newest smart home device. The Smart Air Quality Monitor is built to keep tabs on what you're breathing when inside. It measures five factors, including particulate matter, volatile organic compounds, carbon monoxide, humidity, and temperature, and displays them on the Alexa app or an Echo Show. It'll keep track of your home's trends, and when levels get to an unhealthy number, your device will alert you and provide tips to improve the air quality. Amazon's Smart Air Quality Monitor is currently available for pre=order and will ship out sometime in December.
