Project Description
This project strived to deliver a robust prototype of a truly automated home system - a Smart Garden. This project leveraged the EZ-BT Bluetooth Mesh Development Kit and showed how multiple nodes can be used in a smart home to do different tasks: Turn on LED lights when motion is detected, control the opening and closing of a gate/mailbox and actuate an irrigation system. It also showed the benefits of Bluetooth Mesh networking and Cypress solution - as all of these different nodes were controlled by a modified version of Cypress' reference Android Mobile App. This project took things a step further and interfaced the Mesh App with Twilio's Messaging API so that a user would get WhatsApp messages when the irrigation system was turned on for example.
