This is an educational hands-on project wich consists on developping a real-time digital layer for a community urban garden. We use triggers to launch alerts and twitter messages to support garden long term maintenance. All the information from the vegetable boxes is being published on Cosm, so that it can alert end users using Twitter triggers from cosm when the value of humidity might go under a certain value. It will communicate to the community that more water is needed, so they will have to take look at the plants.

We developed this workshop at CICUSLab in Sevilla. CICUSLab promotes projects related to technologies, digital culture, cities and arts. It is part of the “Centro de Iniciativas Culturales” of the University of Sevilla. Next some links about the workshop Jarduino we run in November 2012:

Educational objectives of the workshop.

1. Into the Data Making. Understanding how real time data is gathered into Cosm. Introduction to triggers and visualization applications from Cosm. Settings triggers to send twitts.

2. Learn basics on DIY Electronic. Arduino and Nanode platform. Breadboard and PCB. Soldering. How do sensors work. Main concepts. Fun.

3.Interaction. How can a community be helped on the maintenance of the farm/kitchen garden/vegetable path by using DIY Arduino based device ? All the information from the vegetable boxes will be published on Cosm, so that it will alert end users using Twitter triggers from cosm when the value of humidity might go under a certain value. It will communicate to the community that more water is needed, so they will have to take look at the plants. In the futre we will also try to mashup data from the Spanish Agency of Meteorology (AEMET) to make the device “aware” of anomalous conditions to alert users and trigger preventive actions, like moving motors to cover the plants in an extremely windy day.

What you need to build this device.

Conclusion

This workshop has been a great opportunity to develop real-time services using Cosm along university students, that will be used for a long time by a wider community. We will continue working on projects with plants and shared responsibility/awareness.
