That's all for this article, keep in mind that you can use what you've learned in this guide for a lot of other fields than gardening! You can connect multiple sensors inside & outside of your home to the Carriots service, and create more complex conditions to send specific alerts based on the data you are recording. Have fun with the project, experiment with this cloud service, and share your creations!
