Project: Air Pollution Index Station

Air Pollution Index Station is a custom designed and 3D printed weatherproof system for a commissioned project, to measure levels of air pollution near a school garden. The measured data would then be visualised and analysed in the cloud. Plants were dying at certain times of the year and there was a need to find out the exact reason of pollution, as well as the amount.

This is an image of the initial prototoype. I was initially experimenting with solar panels, but due to sunlight restraints and eventual power supply and reliability issues, the solar panels were eventually dropped in favour of a more stable, continuous DC power supply.

Visualisation of pollution levels such as PM2.5, humidity, temperature happened in the cloud on the ThingSpeak IoT platform.

This was the design of the final case to be printed in 3D ABS filament using a FlashForge FDM printer. The louvres proved to be lightly weatherproof from rain.

The Air Pollution Index Station was eventually commissioned by the client, and data was made public to managers of the garden.
