There is a growing number of people sharing gardens in Montreal. As a lot of people share apartment buildings, it is indeed more convenient to share gardens than to have their own.

What it does

With that in mind, we decided to create a smart garden platform that is meant to make sharing gardens as fast, intuitive, and community friendly as possible.

How I built it

We use a plethora of sensors that are connected to a Raspberry Pi. Sensors range from temperature to light-sensitivity, with one sensor even detecting humidity levels. Through this, we're able to collect data from the sensors and post it on a google sheet, using the Google Drive API.

Once the data is posted on the google sheet, we use a python script to retrieve the 3 latest values and make an average of those values. This allows us to detect a change and send a flag to other parts of our algorithm.

For the user, it is very simple. They simply have to text a number dedicated to a certain garden. This will allow them to create an account and to receive alerts if a plant needs attention. This part is done through the Twilio API and python scripts that are triggered when the user sends an SMS to the dedicated cell-phone number.

We even thought about implementing credit and verification systems that allow active users to gain points over time. These points are earned once the user decides to take action in the garden after receiving a notification from the Twilio API. The points can be redeemed through the app via Interac transfer or by simply keeping the plant once it is fully grown. In order to verify that the user actually takes action in the garden, we use a visual recognition software that runs the Azure API. Through a very simple system of QR codes, the user can scan its QR code to verify his identity.
