|Description=<translate>Digital Environmental Education (DEEDU) aims to produce educational resources for the youth work sector,

on the topic of environmental science and tech. The strategic objectives of the project are:

promote youth work, combine the benefits and relevance of environmental education with the strength of digital tech, boost young people's maker mindest, provide young people and educators concrete tools to engage in citizen science

The consortium aims at prototyping an educational kit that allows young users to act upon their own environment in view of tackling environmental issues such as excessive energy consumption, air and water pollution.</translate>

{{Introduction
|Introduction=<translate>The automated gardening kit is a system that allows controlling and automatic watering of a small plant. This system is developed for an educational purpose, the plant shall stay at different pupil's house to be controlled.

The user will take notes every weeks from the control panel to create a database to folllow the growth of the connected plant 


What does it control ?

-The moisture of the soil, this value will be directly used to decide whether to water or not

-The CO2 concentration

-The intensity of the light

-The temperature and the humidity of ambient air 


'''What action can be performed ? '''

-A water pump will get water from a small reservoir to put it on the plant

-A screen will display the information needed and 2 buttons to control what info to be displayed

The connection of Arduino on Water pump power supply The Arduino is to be connected directly on the water pump power supply so the whole system need only one electric plug to works.

The Water pump is a 5V power supply, the arduino can support that voltage but this leads to a warming of the internal component of the arduino and will possibly damage on the arduino with time. The easiest and fastest choice for now is two 5v power supply (one for arduino and one for the pump)

For using only one power supply like a 12v one, some solution are linked below

In this section is presented how shall be used the Deedu system and what will be the response at different cases

UC01 : Control data from sensors & Number of spraying By using one button and looking on the screen, the user shall be able to check instantly the value measured by all sensors.

UC02 : Spray the plant when needed & Water tank level control

The system should be able to water the plant when it's needed (The moisture sensor value indicates when watering is needed). The water pump is tricky to start (if no water is present in the tube, it won't be powerful enough to start), so the best is to prevent absolute emptiness of the water tank. Therefore in order to control the water level and prevent water from pumping if water level is too low. The user will get a warning to fill the water tank.
