There are approximately 2400 instruments at Itaipú Binacional, of which only 10% are fully automatized. Additionally, most of the data come from manual input by technicians. In this context, a mobile application has been developed to help in the Dam Auscultation, making it possible to collect and visualize data on the field, along the Dam, in real time. With this application, the technician can input a new measurement in a secure way, knowing that the application does outliers verification. It's also possible to verify the last values of each instrument and even locate them through georeferencing.
