Nowadays there is much talk of the smarts cities, where you want to fill the city with sensors so that we can make life more comfortable. In this Project, different types of sensors have been studied because they can be used for this new concept. The objective of this TFC is to analyze some sensors given by the company Nebusens (www.nebusens.com) and to check the following aspects: · Correct operation of the sensors provided. · Analysis of the degree of difficulty in the operations. With all these tasks done, an application has been made to study the different types of estimators that are used for an indoor localization application. Once elected the estimator that provides better practical results, the localization has been improved using the sensors provided by Nebusens. Finally, with the sensors of the Kit, it has been studied which of them permit a better car detection in a parking lot.
