The Birth of Guardian! 

The AirGuardian Node is a compact, cost-effective, and easy-to-build device that combines the power of a Raspberry Pi 4 with the precision of the SDS011 air quality sensor. By leveraging the capabilities of the Streamr Network, the AirGuardian Node allows users to collect, store, and share real-time air quality data from various locations. This information can be utilized to identify pollution hotspots, evaluate the effectiveness of emission reduction strategies, and raise awareness about the importance of clean air.

This project provides a real-time monitoring system for earthquake events using data from the EMSC (European-Mediterranean Seismological Centre) RSS feed. The system retrieves earthquake data, processes it, and streams it to a Streamr node using MQTT. Users can subscribe to the Streamr node to receive real-time updates on earthquake events as they happen.
