Workflow Description

1. Monitor Air Quality

The Airgradient device continuously measures air quality parameters such as PM2.5, PM10, and VOCs.

2. Detect Change

The system analyzes the data to identify any significant changes in air quality that exceed safe thresholds.

3. Send Alert

If unsafe levels are detected, an alert is sent to the homeowner’s smartphone or smart home system.

4. Activate Air Purifier

The system can automatically trigger connected air purifiers or ventilation systems to improve air quality.

5. Log Data

All data regarding air quality changes and actions taken are logged for future reference and analysis.

Postconditions

After the capability completes, the air quality is continuously monitored, and appropriate actions are taken to maintain a safe environment, with the homeowner informed of any issues.

Optional Enhancements

• Integrate with additional smart home sensors for comprehensive environmental monitoring.
• Implement voice commands via smart assistants for quick access to air quality data.
• Set up custom routines based on air quality changes, such as scheduling air purifier operation.
