autoregulated greenhouse

Hello everybody,

As you could see last week, our project is completely functional. So, during the last project session, we were working on the pump’s regulation and on the possible and attractive improvements.

The first thing about we worked was the water flow regulation from the pump. Indeed, the pump was replaced by a led last week. As a result, we wanted to work on this feature to improve our quality’s model.
Thanks to an continuous external power plant (9V) and a mosfet transistor, we manage to adjust the ground moisture by the water flow out of the pump.
Thus, the humidity regulation is functional now as well.

The second part we were working on, was the development of a manual mode to command the different actuators (pump, stores and windows). This mode is totally functional now.

To resume, everything works and is assembled with the greenhouse structure. Consequently, only the final video has to be realized for the next project session.

The Cocktail Maker Machine : you will be able to buy it soon!

On monday the third of May

This Monday, we continued and finished our program.

Some buttons were changed, and a kind of menu was programmed.

Our teacher Ms Baclin accepted the functionalities of our project. So all the lights are green to continue our Cocktail Maker Machine!

The model didn’t evolve for the last weeks… Thus, next week, we are going to finish the model. Then, everything would be done, at least be in working order.

This week, two guys of the team were busy to draw all the Arduino connections to help us to redo the wiring on the model.

We don’t have to forget shooting some videos to edit a short (between 5 and 10 minutes) presentation film about the project.

During this lab session, we took some pictures of our work. Next time, we are going to shoot some videos.

To conclude, our project is progressing well, but we it’s not finished yet!

Enjoy your life, enjoy a cocktail!

Nearly the end of the project !

Hi everybody !

We are sorry for the late, but don’t worry, we are here and we will tell you what we did this week.

We finished all our programs. We had a big problem with the screen. The word was displayed two times. In fact the communication from the arduino to the Raspberry Pi and in the opposite way were good but not the 2 ways together.
Thanks to Mrs Baclin’s help we solved this problem. In the program we count the number of charachters in the word and we send it to the arduino. In the arduino we cut the word recieved from the Raspberry Pi to have the good lenght and it is juste one time displayed. It doesn’t solved the problem but it avoids it.

We worked a long time on this program because of this communication problem. On friday we began to put all the programs together. It is not finished and need to work à little to finished the program.

About the screen, the display of the different functions (enrolling, lecture and delete) works. In the first time, the screen will just allow the lecture. But in the future it will be possible to enrol and to delete somebody with the screen.
We see the end !

Next week we could make our video.

See you!

Hello everybody,

This week, we will focus our meeting on the drawing of the wiring diagram representative of our project.

Here is the first part of our summary of budget:

items Prices
plexiglas 18,00 €
battery 16,00 €
transistor&connector 9,00 €
cable 6,00 €

Just here there is a picture of the plexiglas. Normally it’s free but we don’t know why, we had to pay 18 euros for this piece. It’s not expensive so it’s not a big problem.


Regarding to the model, we are going to use a box of wine (in wood) or a bow of shoes. It’s easy to cut inside and place the screen, the baffle and the touchpad. It’s also an easy way to reduce the budget of our project.

That’s all for today.

Don’t forget to follow our progress next week.

See you soon.

Explaining of our project: REGULATED GREENHOUSE

To set the context the video linked, it is necessary to remind our project. We are working on the auto-regulated greenhouse. The regulation will perform according three parameters: the luminosity, the temperature and the humidity. At this moment, as you can see on the small movie, everything is functional. Moreover, all of these parameters are sticked on a plasma screen. The last thing that needs to be done is the assembly with the greenhouse structure.

Temperature’s parameter
The temperature is very important for the vegetables growing. The temperature can be to high in summer to prevent for the vegetables life. As a result, our Arduino’s system will adjust the temperature thanks to the opening of windows to get fresh air and thus, decrease the temperature inside. If the temperature sensors get a too high temperature, the opening is performed thanks to 2 servomotors linked to the window’s hinges. Depending of the greenhouse temperature, the windows are more or less opened.

Humidity’s parameter
The humidity is essential for a good vegetables growing as well. In fact, the plants don’t have to be thirsty otherwise they die. In the present project, this parameter is also regulated. In fact, if this parameter is not enough, the Arduino’s system set an hydraulic pump on to distribute water to vegetables. If this parameter comes back to a right value, the pump stops. Obviously, the water flow varies according to the humidity shortage. We had to use a mosfet transistor and a electric relay to be able to provide electrical energy enough to the pump. Indeed, our Arduino couldn’t provide a sufficient tension to set in motion the motor’s pump. On the linked movie, the pump is not present and has been replaced by a led. However, it is functional because we can see the luminosity variation according to the humidity level.

Luminosity’s parameter
This parameter is critical for the vegetables. Indeed, the luminosity can’t be too high because it could lead to the leaf burning and thus the death of the plant. This is the reason why we decided to regulate factor thanks to the rolling of stores. As you can see on the model on movie, when the luminosity sensor detect a too high light, the Arduino’s system commands motors linked to stores to protect the vegetables against the sun rays. In our project, we will simulate the store’s rolling with some leds while be activated when the stores must be rolled.

see you next week

Progress report

Hello everybody,

This week we haven’t had any lab to work on our project but we worked on it while we were having break.

We still have some difficulties with the communication between the Arduino and the Raspberry Pi. It is our biggest issue at the moment. The next step is to finish this point. Indeed, when this point will be finished we will be able to combine each program.

Moreover, the fingerprint program works! Last week we had some difficulties with the three positions switch. Indeed, this button is used to choose the part of the program you want to use. Last week, we assembled the different programs but when we wanted to change the program, it wasn’t working. So we tried to understand what was happening. We found the solution. Actually, there were mistakes in the programming and the wiring wasn’t working well. Wires weren’t entirely connected because we always have to move out the scale model. But now it works. This means that you can change the program before continuing further with the chosen operation and you can also change the program once the operation has been done.

Then, we have also worked on the classroom’s schedule. Now we can extract all information we want in the intranet file. We will now try to send e-mail from the raspeberry to the e-mail address extracted from the intranet file.

So all of our programs, except for the communication from the raspberry to the arduino, work lonely. We know that the next step will be hard too. Indeed, we’ll combine each program in order to complete the project. We will probably tear our hair out but we can do it and we will do it.

That’s all for today,

But don’t forget to follow our progress next week,

See you soon.

See you soon,
