This Raspberry Pi project looks like a toy but it's actually a useful air quality reporting system. It was created by maker Dmytro Panin who used a toy traffic light alongside a Raspberry Pi 3B+ to create the final design.
The best Raspberry Pi projects improve our quality of life and this project is no exception. According to Panin, his area is currently experiencing a season of peat fires which can cause the smog levels of the city to increase dramatically and unexpectedly. This project aims to reduce unwanted exposure to higher pollution levels.
