DESCON 4.0 Winning Product

DESCON 4.0 IoT Hackathon developed several air quality monitoring prototypes. The one we have kept working on is now ready for deployment by citizens.

The winning team members along with DESCON founder, Des, are excited to unveil their new open-source software and hardware product.


Phase 1

DESCON’s aim in 2018 was to inspire global climate action with their theme: “Saving the world one hack at a time”.

So as to fulfil the challenge, the winning team set out to create a citizen science project and network for the region in order to gather more accurate air-quality data. They wrote an open-source code and constructed an open-hardware portable air-quality monitoring device, designed to be crowd-sourced, mobile and affordable for citizens.

The prototype consisted of an ESP8266-based NodeMCU board with a Sharp GP2Y1010AU0F air-pollution sensor.

As this year’s winners, two members of the team, Vanja Stanic and Filip Parag, were awarded a fully-paid trip to ThingsCon, held in Rotterdam in December 2018.


Phase 2

The next phase was dedicated to upgrading the firmware of the device, allowing for improvement in the reliability and stability of the product by using new generation sensors.

Other add-ons included:

– a display showing measurements

– more efficient battery consumption

– option of battery or electric power

– ability to send data to a cloud server


Phase 3

In phase three, we are currently simplifying the product and making it more consumer-friendly. This will include an easy-to-build kit that allows anyone to build and install the device.

We are continuing to improve data accuracy by using even newer generation sensors measuring PM 1, 2.5 and 10. Additionally, we will include sensors for humidity, temperature and air pressure.

To improve on the design, the hardware will be housed in a simple weatherproof 3D-printed enclosure. We also plan to make the device CPE friendly and even more cost-effective.

We hope to have this phase completed prior to DESCON 5.0, October 4-6, 2019.
