Our friend, Jordi has shared his WSN project. He showed us his project last weekend in Arduino Barcamp Zaragoza 2012 and it was very popular in the event. In this project it is designed and implemented a control and remote supervision wireless system having as a core technology a wireless sensor network. The main features of the system are that is based on a modular solution, being low cost, energy ecient and that preferably makes use of open source technologies.
The system includes also a supervision level which is based on a SCADA application which can be accessed remotely by any web browser for supervision and control purposes of the process. It is also developed an alarm notication system based on text messages sent by SMS to mobile phones.
As a summary of the technologies involved in the development of the current project, the protocol used for communication in the wireless sensor network is Zigbee, and for the supervision level are used mobile communication protocols such as GPRS and GSM. The micro-controller is based on the open-source electronics prototyping platform Arduino. The SCADA application is programmed in HTML and PHP languages, and all the information of the system is stored and accessed from a MySQL relational database.
