The project involves the development of an electronic device that is able to communicate locally with mobile devices using a USB interface, such as, cell phones, netbooks / notebooks and tablets. In addition, it must acquire data from sensors and use the remote communications capability of these mobile devices to send the acquired data to a central server. To do this, the module must have capabilities for a USB host and device, as well as AD conversion and serial interfaces for sensors. Today, we have developed a module with USB embedded host capability, establishing a local connection with a cell phone with a USB interface that can send text messages as a means of remote communication, implementing AT commands. This module also implements a USB device to communicate with mobile devices capable of hosting (netbooks / notebooks, tablets), which for now are only used for configuration and data acquisition
