From Gas Detector to Fume Extractor

As you know, in August 2019 I created ANAVI Gas Detector - an open source Wi-Fi dev board for monitoring indoor air quality and detecting dangerous gases. Thanks to your support during the crowdfunding campaign here at Crowd Supply it became a reality. If you take a closer look at the development boards of ANAVI Gas Detector and ANAVI Fume Extractor you will notice a lot of similarities. If you, like me, also like soldering, hurry and place an order during the crowdfunding period to be among the first owners of ANAVI Fume Extractor. Read the full update.
