ANAVI Gas Detector – An ESP8266-powered air quality monitor

ANAVI Gas Detector is an ESP8266-powered, open source, Wi-Fi dev board for monitoring air quality and detecting dangerous gases.

ANAVI Gas Detector is an ESP8266-powered, open source, Wi-Fi dev 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. All these features make ANAVI Gas Detector appropriate for developers, makers, students and open source enthusiasts interested in home automation.

ANAVI Gas Detector is fully compliant with Arduino IDE, PlatformIO, the popular open source home automation software, Home Assistant via the lightweight messaging protocol MQTT and ThingSpeak, the open IoT platform with MATLAB analytics. With ANAVI Gas Detector it is easy for developers to focus on the software by easily building and flashing their own versions of the source code. Tech savvy users can easily integrate ANAVI Gas Detector in their existing open source home automation platforms.

ANAVI Gas Detector is an entirely open source project that combines open source hardware with free and open source software. KiCAD and OpenSCAD were used to design ANAVI Gas Detector. Source code and schematics are available at GitHub. All units will be manufactured in Plovdiv, Bulgaria. Getting started with ANAVI Gas Detector is easy. No soldering is required. Comprehensive user’s manual with exact steps for using ANAVI Gas Detector will be provided.
