Customer story of Airthings

Wave Plus is a battery operated indoor air quality monitor that uses six sensors (Radon, CO₂, Humidity, Temp, VOC, and Air pressure).
Wave in front of the device for a color-coded, touch-free visual indicator showing air quality levels. 
In the case of CO₂, it will blink in green when it is 800 ppm or less, yellow when it exceeds 800 ppm, and red when it is 1000 ppm or more. 
The long battery life supports 16 months (Bluetooth^®*) or 18 months (SmartLink) average with two AA batteries.
Free apps and online dashboard can display monitor numbers, graphs, and easy-to-understand indicators.
Make your smart home a healthy home with Amazon Alexa, Google Assistant and IFTTT. Connect into your smart home: set alerts, receive air quality measurements, give voice commands, connect to a smart plug or smart product to control your thermostat, air purifier, or humidifier - the options are endless.

Wave Plus relies on industry leading CO₂ sensing technology-based “Sunrise” developed and manufactured by Senseair - an AKM group company.
