This easy tutorial helps you to control the water used in your garden watering. To do this, we use Arduino and Raspberry Pi to get the best of both.
In this project you will learn how to:
- Communicate Arduino with Raspberry Pi
- Read a flowmeter pulses
- Connect a Raspberry Pi to Carriots to send data streams using Carriots HTTP REST API

This is the project schema.
On future parts of this tutorial you will learn how to analyze data and to control a valve to automate your gardening.
This is unit we prototyped in our lab:
And the electric schema:
Check the turorial for the source code we used to make it work.
Enjoy it!
