Environment Monitoring Unit with Wi-Fi Interface

Aim of this thesis was to design and realize embedded platform for monitoring indoor environment. The device can measure indoor and outdoor temperature, relative humidity, atmospheric pressure, concentration of carbon dioxide and other flammable gasses. Its output can be viewed on a graphic display or via web interface (Wi-Fi Access Point). In this thesis you can find an overview of current competing products and their comparison with our measuring unit. Furthermore, a hardware and software design is added here along with the testing measurement and its analysis.
Keywords: indoor air quality, CO2, ESP32

Complete operating unit in a transparent box (with many drilled holes to allow air go through…)
PCB with the environmental sensors and WiFi module, without the display and motion sensor
www interface
CO2 during the day in small room… (the author went to the bed around 1 a.m…)
