Automated Greenhouse




Introduction: Automated Greenhouse

We decided to design a greenhouse as subject for our electronic project. The goal was to regulate the temperature inside the greenhouse thanks a lamp, a servomotor to open a window and a PC fan. We wanted to maintain a quite constant level of soil moisture with a pump and to receive temperature, soil moisture and luminosity measurements. Finally, we designed a website to be able to control it remotely.

This project was made for our electronic course and we wanted to use a raspberry pi and an arduino board. We know that it can be improved in so many ways but we want to give you ideas to redo it and improve it.

Step 1: Presentation

This greenhouse has different sensors to measure the ambient temperature, the external temperature, the soil moisture and the luminosity.

The ambient temperature sensor allows us to start the fan and to drive a servomotor to open the window when the internal temperature is above the temperature setpoint. Conversely, if the temperature descends under the temperature setpoint, the fan is stopped and the window is closed. Furthermore, a lamp is switched on to warm the plant. The soil moisture sensor allows to drive a pump and an electrovalve for the watering system when the earth is too dry.

Thanks to a USB cable, the Arduino uno board is connected to the raspberry 3 board. This connection allows us to recover the measures and the states of actuators. These data are stored in a mysql database. A script in python allows us to communicate with arduino uno (master/slave communication) and save the data in the database or read the database and send new values in the arduino.

Next, an apache server is installed on the raspberry in order to host a website. With the help of php, we can make the bridge between the mysql database and the website.

On the website, we can define the temperature and moisture setpoints. It is also possible to control each actuator manually and to look their states.

Step 2: List of Components

We wanted to use as much as possible components stemming from the recycling

Step 3: Coding

For this part, we give you the different programs and code that we made for this project:

Arduino's program:

The new version is now available. The issue with the window is now fix and some little bugs.


We installed the MySQL server and the Python bindings for MySQL. For the web server we installed the Apache2 package


The CSS files are now available in the .rar folder.

Raspberry script:

For this script, we used the MySQLdb library. You need to use python 2.7 to be able to run the script.

The script is the bridge between the arduino and the raspberry pi. It allows us to save the data from the arduino bord into the database and send the new setpoint values defined by the user into the arduino program.

Step 4: Mounting

Step 5: Wiring

Step 6: The Website and Database

EDIT: The new version of the website is now available.

The website that we disgned is composed of three pages.

The first one is the main page. With this page, the user can see the states of the devices and the different measures.

The second page, Commands and parameters, the user can easily change the device's mode and switch them on or off. The setpoint values and the parameters can be changed on this page too. For the parameters, we validate the new entered value to be sure that it is correct.

The last page is just about us.

Our database is made of three tables. The "mesures" table is dedicated to the collected data storage.

The "types" table contains the parameters of each measurement and the "commandes" table allows us to control the devices and to know their state.

Step 7: Time to Save Your Time and Your Plants

This is it! You have all the tools to make your own automated greenhouse !

You can take a look to the video to see the automated greenhouse in action.

sorry for noob question .. where is the sql file (db_basilic)? i have download the 3 file but cannot find the sql file .. i need this for my thesis .. thank you in advance


How can obtain all this components with one order?...Is it necessary to have remote control for the system?..what i want is to leave alone the sensors to do their job. I would like to activate the system only pressing a switch.

thank yoy

nice project..

How to connect raspberry with arduino?

The project is beautiful and wonderful but you can explain to me how to connect the Arduino device to the site on the computer

this is my email:

Thumbs up guys

I am thrilled with the presentation from hardware to software details. I am tasked to do a project on this topic, may I ask that you assist me in terms of block diagrams from inputs to outputs and details of the interfacing circuits to the controller boards.

my email..

nice one.

i want do these project part of my academic year final year project i have lot of confusion can you explian where to i am start what is the process and all other things .

my mail

Salut, auriez-vous des plans plus explicites pour la réalisation de votre serre ?? Comme par exemple un plan plus détaillé pour réaliser la fenêtre!!


Im very new to micro controllers and website hosting, but what do you do with the website files in order to have them run on the Raspberry Pi?

What is a socket and a connecting box? And where can i buy them? Can i have a photo of the two components?

Hi,this is a great project! Could you do a clip when you mount all the components? This would help a lot! Thanks! Anyway my mail is

hi kindly email me the english version of all the codes THANKS .

1 reply

Jasmin, I doubt that anyone would make a seperate program with english comments :-)
Anyway for the compilation it shldnt make any difference, but maybe for yr understanding it would.
The remarks appear to be french, cant google translate help? is there an specific word you are struggling with?

we're having a hard time translating the codes to english ... please help us .. thank you !!!!!! EMAIL ME

please email me the english version of all the codes .. we are currently doing this project .. we just don't understand why it came up with that kind of language , email me

Great project. Can you post the list of components with the relative reference to buy it on internet. thanks a lot.

so the script is run using python


this is easy use my PC to put code to the arduino

I think I have php5 installed,

not sure how to test php5

I have Apache2 installed

when I go to a web page

I see

It works!

the default web page


I can not get my PI to extract an RAR

I had to do that on a windows

you should use tar files

so where do move the extracted website.rar files too on my PI

in order to get it to work

Then I run python script, right?


there is another version built by Technarium hackerspace

While more expensive than a servo. You could use a stepping motor for your venting. You just need two pieces of acrylic with slots. This way depending on how they overlap you can vary how much air is allowed to escape. This way with some testing you could figure out how many steps the motor needs to do for specific temperature drops for different types of plants.

Is your green house suitable for growing auTomatoes?

Just kidding, great project!

Other than a technical remark, let me also make a growers remark.
As the housing is of clear plastic, obviously it will receive its light from the sun. The lamp, i understood, is to maintain temperature. Beware though that this means that if it is night, and the temperature drops the lamp might go on disturbing the dark/light rhythm eventhough it is an IR lamp. Though for some plants this is not a problem, for other plants it is.

There is an LDR, so I guess there is a possibility for protection against that (not switch on the lamp when it is night) but that might be defeating the purpose. Consider a ceramic heater.

When checking the software, I came upon some statements that were more complicated than necessary. e.g.

if (temp_int <= (tempmoyenne - deltat))
chauffage = true;
if (temp_int >= tempmoyenne)
chauffage = false;
if (chauffage == true)
cmdlog7 = 1;
cmdlog7 = 0;

couldnt this be replaced by:

if (temp_int <= (tempmoyenne - deltat))
chauffage = true;

cmdlog7 = 1;
else // or if really necessary: if temp_int >=tempmoyenne)
chauffage = false;

cmdlog7 = 0;
I am not sure what values 'deltat' can have but if it is 0 your loop gets confused. Unless it is really necessary to have a state in which your chauffage is false but your cmd7 is still true
