An exchange project has been set up between Universcience and the Cluj Cultural Center in Romania, as part of the France-Romania season. The first part of this exchange consists of a FabLab residence of two Romanian Biologists from the University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, who, together with the Carrefour de Numerique team, will work on building up a fully automated terrarium. The residence runs from March 19th to 23rd.
Once the Terrarium is in place, the objective of the residence is to be able to check & register the parameters of soil & air humidity, air temperature & ventilation as well as the light-intake of the terrarium and to build up an automatized system for watering, heating/cooling, lighting and air flow in the terrarium.
The system will also be used to study different aspects of the Terrarium Eco-System. How do plants affect each other, what is the correlation between humidity, temperature and light intake, what are the optimal humidity, temperature and light values for a favorable plant growth?
The second step of the exchange project will be concerned with setting up a web application for controlling the Terrarium remotely. For example, when we go on vacation, we stop watering our plants and turn off the heat. The temperature dropping and the humidity decreasing over a longer period of time, could be dramatic for the plants. Controlling the terrarium remotely over the phone or computer could save a lot of plant lives!
To set up the terrarium technically, you will need :
We chose to use an arduino uno to control:
We use RGB LEDs that have one commun cathode.
