#SmartCities Hack Winner Showcase: Team GTPLUS & WYHIL #3

This is the fourth in a six-part series which will showcase the projects built by the Top 6 teams of the #SmartCities Hackathon. The Smart Cities hack was a two event hackathon organized by Hackmakers dedicated to finding innovative solutions to generate more awareness, stronger communications and quicker responses for tomorrow’s smart cities.

​Team GTPLUS & WYHIL has come up with a preventive solution called ‘Covid-19 Pandemic Prevention’ for respiratory diseases like Covid-19 using Oracle Cloud tech (ADW and OAC). The team ranked #3 among all the participants in the hackathon.


Challenge Addressed

Safe Cities

Safe Cities requires an understanding of the need for security to evolve from a reactive to a proactive approach, with integrated response. The Safe Cities Challenge category can cover solutions that help cities to manage public security issues as a city population and urbanization grows.


Problem Statement

According to a report by the US Environmental Protection Agency, people are spending 90% of their time indoors and the concentration rate of air pollutants indoors is 2-5 times higher than outer air pollutants.

Risk of Covid-19 infection increases when either concentration of CO2 or Aerosol rates are high. The CO2 concentration rate is one of the most important indicators used by indoor air management systems to measure air quality. When a person infected with Covid-19 talks or sneezes, droplets and aerosol spreads into the indoor space.



The project, ‘Covid-19 Pandemic Prevention’ provides a preventive solution for respiratory diseases like Covid-19 using Oracle Cloud tech (ADW and OAC).

To prevent respiratory diseases such as Covid-19, the team has come up with an indoor air quality antivirus management system and untact/automation AI/AIoT indoor air quality management platform.



Team GTPLUS & WYHIL applied ‘The Swiss Cheese Respiratory Virus Pandemic Defence Theory’.

The given theory suggests a step about ‘managing indoor air quality as a mark’, which can be done without having much expertise in medical science.

With the right approach and implementation of right tools, the team aims to prove that IT technology can contribute to the prevention of Covid-19 by using Oracle Cloud Infrastructure.


How Does it Work?

The Oracle Cloud Infrastructure Architecture –

  • Collecting CO2, fine dust, TVOCs, temperature and community data in real time by using WYHIL airfield device

  • Using OCI streaming service, to collect real time mass data and store data to object storage service

  • Using OCI function service, for data processing and then store it to autonomous data warehouse

  • Using Oracle Analytics Cloud, to make graphs, charts and maps to monitor data from ADW efficiently

  • Setting and Applying system to monitor data from various angles from many different situations

  • The OAC dashboard would now show the numbers, location and operation rate of devices which get the information of selected locations

  • If a specific location is selected, we can get its operation rate. This would allow us to check if there are any blind spots in the whole air quality monitoring system in real time

  • Selected places are plotted with factors such as early CO2 concentration, temperature and humidity measurement for selected time range. Based on the analysis of various factors, we can check at what time the concentration levels are high and take appropriate measures accordingly, as per the guidelines

  • When data shows that the levels have exceeded the threshold, the system could send an alert to the user or operate on an automatic ventilation system.

This can efficiently contribute to Covid-19 prevention and prove the effectiveness of a Smart City’s automatic healthcare system for its citizens.
