Météo Sociale or Social Weather in english was made at school with 5 friends. The brief was to show live datavisualisation of our school in a website. We decided to use sensors connected to an Arduino. All collected data is sent to the server and each of them are interpreted visually into a weather icon. Well on the website we can see in live the mood school activities. The more the weather is beautiful the more there is social activity. On the contrary if there is no activity the illustration in real time is dark and rainy. We had the chance to participate at Maker Faire 2013 at Rome so we decided to continue the project with a sixth person who helped us for the programmation.
