Meet the Keyco Air: a smart air quality monitor plug that detects airborne toxic chemicals in your home. It uses an app and LEDs to keep you in the know. The device is SmartThings and Alexa compatible. It can test your air for chemicals such as black carbon, nitrogen dioxide, aldehyde, methane, and ammonia.
The device detects temperature and humidity too. It can combine with your smart air purifier to make sure you breathe better quality air at home. Simply plug in your Keyco Air into an AC wall socket, and you are ready to go.[HT]
