This is the fourth video of my tutorial series on how to build your own “Flaura”, which is my Do-It-Yourself, Open-source project.

Flaura is a smart, self-watering plant pot that comes with the following features:
- 3D printed housing
- Integrated water tank
- Soil moisture measurement
- Automatic watering
- Rechargeable battery
- Arduino Code
- App control and data display
- Push notifications

Consider watching the introductory video, to learn more about the features and my future plans with Flaura:
