ANAVI Gas Detector Default Arduino Sketch

Open source Arduino sketch for the smart WiFi dev board ANAVI Gas Detector for MQ gas sensors.

ANAVI Gas Detector is an open source, easy-to-use, Wi-Fi compatible development board for monitoring air quality and detecting dangerous gases. It supports popular analog MQ gas sensor modules such as MQ-135, MQ-2, MQ-3, etc. Furthermore, it comes with slots for mini OLED display and up to three additional I²C sensor modules, including the precise digital sensor HTU21D for measuring temperature and humidity.

Air pollution is a very serious problem. Monitoring air quality and detecting toxic gases can improve one’s quality of life. All these features make ANAVI Gas Detector appropriate for developers, makers, students and open source enthusiasts who are interested in home automation and an environmentally friendly lifestyle.
