Description

I noticed during home office times as well as with multiple people in one office how quickly air quality drops, which affects concentration and finally performance, as it causes tiredness and headache. I want a device that continuously measures the quality and reminds me in time to make adjustments to the airco (if available) or when to air the room, or take a break outside. 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, ...

Todos

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.

Outcome

Item completed and functional, documentation of the above and published under an open source license to allow others re-create.

Resources

ESP32 development board, MH-Z19C (CO2), BME680 (temp, humidity, pressure, quality), SSD1306 display, breadboard.
