Guardian is a decentralized air quality monitoring and seismic activity detection system. The project leverages cutting-edge technologies, community-driven efforts, and open-source principles to provide real-time, accurate, and reliable environmental data.

#### Problem

Air pollution and seismic hazards pose significant threats to human health, safety, and the environment. Traditional monitoring systems are often centralized, expensive, and lack comprehensive coverage, making it difficult for communities to access and trust the data collected.

#### Solution: Guardian

Guardian addresses these challenges by employing a decentralized network of data-collecting nodes, providing a more accurate and comprehensive picture of air quality and seismic activity. The system empowers individuals and communities to take an active role in monitoring and responding to these issues.

#### How is Guardian being built?

Guardian Nodes are designed using Raspberry Pi and off-the-shelf components, integrated with IoT devices, air quality sensors, and seismic activity sensors. The data collected by these nodes is securely and efficiently transmitted using Streamr, a real-time data streaming and sharing platform.

#### Physical Components

- Raspberry Pi: The core computing component for the Guardian Node.
- Air Quality Sensors: Measure pollutants, such as PM2.5, PM10, NO2, and CO.
- Seismic Activity Sensors: Detect ground motion, vibrations, and tremors.
- IoT Devices: Facilitate communication and data transmission between the sensors and the decentralized network.

#### Streamr Integration

Streamr enables real-time data streaming and sharing, ensuring that the data collected by Guardian Nodes is accessible and up-to-date. By leveraging the power of decentralization, the system ensures data security, tamper-resistance, and reliability.

#### Roadmap

We've been approved to place a Guardian Node on the top of the most active volcano in Colombia, once conditions are safe to.  The Nevado Del Ruiz is a Volcano in the heart of Colombia that is known infamously for its last eruption killing more than 25,000 people.  We will build out several MVPs and test them for 30 days until we're confident that mounting a node on the top of the volcano will maintain its data output for an extended period of time.  We then will be seeking approval to mount nodes in areas that are prone to potentially lethal natural disasters like earthquakes and forest fires.
