Tesla STEM High School EESD Raspberry Pi Smart Garden

This repository includes all the code you need to get started with the Tesla STEM Smart Garden (or even one of your own)!

If you are curious about this project, Don't be afraid to email @somebody4545 on GitHub for access to more documentation.

If you are doing this for an EESD project, contact me via a school email on my school email, or when I graduate, contact me with your personal email.

Prerequisites

• Raspberry Pi

  • 3b+ works, there are no CAD files for a case for it
  • 4 has a case created for it

• Assembled system (additional info in our CAD files in the Legacy Project folder)

  • Grove Base Hat for Raspberry Pi
  • One Wire moisture sensor (PIN D5)
  • DHT11 (Humidity + Temp) (PIN D16)
  • SI1151 (Sunlight) (PIN I2C)
  • Relay (PIN D18)
  • 4 Analog Moisture Sensors (PINS A0, A2, A4, A6)

• A domain (unless sticking to fully local)

  • With the domain, it is preferable to use Cloudflare Tunnel as the passthrough solution

Run the Project

Step 1: Set up the RPi

• YOU WILL NEED A WAY TO REMOTELY ACCESS THE SYSTEM!!!!

  • Figure this out FIRST, if you don't have an easy way to do this, you will be finding yourself having to run back and forth a lot.
  • This can be done with Raspberry Pi Connect (recommended), but if you're a bit more technical and feel like it, SSH is also a fine solution.
  • The current system's implementation of this can be found in the less publicly accessible Legacy Projects folder

• Install the Raspberry Pi into the system with the Grove Base Hat, and match the GPIO pins mentioned

• Go to Preferences > Raspberry Pi Configuration > Interfaces and ensure the following are on, then restart

  • Remote GPIO
  • 1-wire
  • I2C

Step 2: Prepare to run

This is the fun part where version changes and other issues can completely ruin it all. If you would like a working venv to work with, the current garden has it already, but I sincerely hope this works and we can all go about our day happy. I am open to help out with this section. It may take longer than you think. Blame Seeed.

Installing libraries

• I created bash scripts to make your job a little easier. Here's a simple one liner that should work if you (and I) did everything right:

  git clone https://github.com/MrChuhal/Smart-Garden-Arduino.git && cd Smart-Garden-Arduino && chmod +x *.sh && ./setupPython.sh && ./setupSite.sh

• I recommend digging in to know what you're actually doing, but this should work just fine.

Bash Script Summary

• setupPython.sh: Sets up a Python virtual environment and installs required libraries.

• setupSite.sh: Installs NVM and sets up the frontend environment.

• run.sh: Starts both backend and frontend servers.

• Restart once it is all completed

Refactor

• This code assumes your Raspberry Pi user's home directory is /home/inesh/, which I doubt. You should be able to Ctrl+Shift+F and click open the menu to find and replace each occurence of this with the appropriate directory. If someone can create a PR to handle this in an easy way, I'd be more than happy to merge it.

Step 3: Run it!

Cloudflare Tunnel

• If you have a domain, this is where you'll have some more set up.
• Here, I'd recommend you do some research on Cloudflare Zero Trust to create a tunnel, and likely on a school network, you'll need to use Cloudflare Warp on top of it (instructions for these are online, and likely more accurate)
• Ensure the port the site points to is localhost:3000

This guide is what you're looking for to create the tunnel

Run script

After the previous set up, installing should be as easy as:

./run.sh

You can run this project fully offline on localhost:3000 if you skip the Cloudflare Tunnel setup. You should now be able to check out the site at http://localhost:3000, or whatever your tunnel URL is!!! Give yourself a pat on the back.

To-Do

• Live camera stream display on dashboard
• CSV export download button
• Editable pump thresholds in UI
