Parameters to measure are at least temperature, humidity and CO2 level. The device should be stand-alone and potentially battery powered, with the option to connect to other devices such as PCs or smart phones through Wifi, Bluetooth, Serial, ...
Select components and document electrical setup, create a prototype on breadboard. Create adaptable software. In parallel create PCB, CAD functional case and 3d-print, and finally assemble.
Item completed and functional, documentation of the above and published under an open source license to allow others re-create.
ESP32 development board, MH-Z19C (CO2), BME680 (temp, humidity, pressure, quality), SSD1306 display, breadboard.
