This project is dedicated to all of victims from Kaosiung gas explosions in Taiwan. When the explosions happen I was in the U.S. I read about the causes from the news. The cause of the explosions due to the leaking of Propene (C3H6). Soon I read of more thing about other causes of the explosions. I realized there is a way to prevent this tragedy if there is a network system to detect this problem at first place. Therefore I started looking for any resource that can help me building a system to archive this goal.

I wasn't able to find a development board with low price from Arduino, Therefore I start looking for other development board. Unfortunately Arduino MKR1000 didn't come out yet. Therefore, I use several different other modules and try to get the data to the Internet. Soon I realized that the connection to several module's will make this project to complicate to get other people involved.

About a year later, I got hired by a company to work on their IoT device prototype. They have Particle Photon as prototype dev board. I successfully help them to build a prototype, however I realized that to use Particle Photon is sent HTTP request to my server will take too much work to do. The work is beyond one man's work. I can't do it along. Therefore I have to temperately put this project always until I can find a simpler solutions to get it done.

When Arduino MKR1000 was published, I see it as a good option to make this project alive therefore I start working on this project from the front-end of the website and the back-end. This is how I get to this contest. This project will be added more functionalities and other sensors in the future. I would like to invite everyone who cares about air quality to join this project. With more people's dedication, this project can help more people's life and make the world a better place.

EXPANDED TECHNICAL DETAILS

Distributed Urban Infrastructure

This Smart City model demonstrates how multiple IoT nodes can work in harmony to improve municipal efficiency and safety.

• Heterogeneous Sensor Network: Managed by multiple Arduinos, the system integrates a LDR-based street lighting grid, a waste-level sensor in public bins, and a soil moisture system for public parks.
• Ubuntu Core IoT Hub: Data from the Arduinos is aggregated on an Ubuntu Core (Snappy) gateway. This hub handles the heavy communication to the DigitalOcean cloud, where a dashboard visualizes the "Health" of the entire miniature city.

Edge Intelligence

• Intelligent Street Lighting: The lights only dim or activate based on detected movement from PIR sensors, significantly reducing energy consumption compared to standard timed systems.
