Story

This project was inspired by the green house at the AWS Loft. Our team got to thinking if we can actually create a way to monitor the health of our plants and get that information in the form of a flash briefing.

The product detects when a person walks inside the green house, and gives a flash briefing of the plant health via Bluetooth speaker.

Data logging

Setup Intel Edison on the breakout board and configure it with your laptop

Connect the required sensors to the breakout board

Download Arduino IDE and paste the code below

Setup espeak on your Edison

Pair your Edison with the Bluetooth watch

Setup a server

Make the Android app

Run the Arduino code

The code pushes data to the Bluetooth watch as well as your android app
