Design of technical specifications of telecommunication, control and fire detection systems for the energy sector. Supply and commissioning revision of the control and communication systems for El Quimbo hydroelectric Project.

:The goal of my work was to coordinate the commissioning of wireless sensor networks projects by acquiring a new platform for data acquisition and presentation, so the engineers would have better tools to improve the administration of the industrial processes. The new platform allowed to reduce the costs by half and it had better performance than the previous platform. In order to implement this platform with success we made test installations in different companies to show the perfect performance of the equipment, resulting in the sale of the first project.
