From the project
This folder contains all you need to build our air quality device!
This folder contains everything you need to produce your own Windy, our smart air quality monitor. The project includes:
⚙️ The physical device with PCB and case
📊 Measures CO2 and TVOC on demand via the app or the device itself
📉 Provides a detailed history and trend of past measures
💡 Provides tips to improve air quality based on your situation
Unfortunately, not all features we intended to implement function correctly. We list here all known issues: - The device collects data only while it is connected to the phone. - The application experiences connection issues in everyday use…
