In this guide, we are going to give a modern touch to gardening and connect some informations about your garden to the Internet. We are going to use a soil moisture & temperature sensor connected to an Arduino and a WiFi chip to automatically send measurements from your garden to the cloud.

We'll use a service call Carriots to handle the data and display it nicely on a webpage. Then, an email or SMS alert can be send to you automatically if the moisture falls below a given threshold. The picture below represents the system when fully assembled and with the sensor buried into the soil next to a plant:
Don't worry, you don't actually need to have a garden or even plants (although we think plants are great to have) to use the content of this article: what you are going to learn can be used for any remote measurement projects. Let's dive into the project!
