Key Features

  • control your garden via web interface
  • log temperature, humidity and soil status automatically
  • control your water pump remotely (or any other device your relais support)
  • full authentication support for security

Hardware Requirements

  • Raspberry Pi 3
  • DHT11 Sensor
  • Soil Moisture Sensor
  • Relais
  • A bunch of Dupont cables

Install

Prerequisites

Before we can run this, your raspberry pi must be set up.

I'll assume you have raspbian running already, and have ssh access or direct access to your Pi.

First we want to update our packages

sudo apt-get update
sudo apt-get upgrade

nginx

This is gonna be our web server that will handle http requests and pass them to our NodeJS application.

Install nginx
sudo apt-get install nginx

Start the service
sudo /etc/init.d/nginx start

Nginx keeps the configuration file for each application it serves in the sites-available folder: cd /etc/nginx/sites-available/

You can either modify the default one, or create your own.

The file should look like this

server {
   listen 80;
   root /var/www/my-app/;                  # identifies the location of the application you are configuring
   server_name my-app.dev;                 # identifies the hostname used by this application's traffic
   location / {
      proxy_pass http://localhost:8080/;   # configures the back-end destination for this traffic
   }
}

Then we can restart nginx to reload the settings

sudo service nginx reload

NodeJS

To download the most recent LTS version use the following command

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

Now we can install it by running

sudo apt-get install -y nodejs

Once this is completed, we can check if node is available by typing

node --version

MongoDB Server

We'll be using mongodb as our database server.

Install it by typing

sudo apt-get install mongodb-server

Then start the service with

sudo service mongod start

You can test if it worked out by typing

mongo

This should put you into the mongo shell, where you can execute mongodb commands

Wiring

TODO

Local Development

If you want to test the application on windows, you should know that you can only test the webapp as we wont have access to the Raspberry Pi GPIO ports if we're not running on the Raspberry Pi directly.

You'll need to have those packages installed on your machine as well:

on raspberry pi the only supported mongoose version is 4.x, due to the last MongoDB x32 version being 2.4. So make sure package.json read "mongoose": "^4.0.14", for your raspberry pi. http://mongoosejs.com/docs/compatibility.html

How To Use

  • pm2: sudo env PATH=$PATH:/usr/local/bin pm2 startup systemd -u pi --hp /home/pi
