In the IoT and Ambient Intelligence (AmI) contexts, these objects currently equipped with sensors and actuators must naturally interact with the user. These sensors or nodes are commonly grouped into the well-known Wireless Sensors Networks (WSN). New smart sensors have emerged to develop this kind of projects, allowing the use of the concept “IoT” and the connection between daily used objects and the digital world. Other applications related to smart farming and the cattle industry have been developed in this domain. These applications can be used in medium and big cities as well as in rural and suburban areas, where this and other kinds of applications based on the IoT are more commonly found. Applications developed for Smart Cities include applications for citizen security and control of people flow in cities, vehicle parking, getting information about accessible places, managing energy of houses and public lighting together with the use of smart grids, water management, waste management, health services, logistics, and a long list of other domains. These cities use a Smart Cities model which aims to achieve more sustainable cities and make cities better places to live in. Nowadays, more and more cities are implementing new systems based on the Internet of Things (IoT) to obtain new data about the city, offer new services and optimize the energetic efficiency. The results of the case study show a developed node with a great lifetime of operation, a large coverage with small deployment of antennas in the region, and a route optimization system which uses weight and volume measured by the node, and provides savings in cost, time and workforce compared to a static collection route approach. Data used for this case study come from open data sources, the report of the Castilla y León waste management plan and data from public tender procedures in the region of Salamanca. This paper presents a case study performed in the region of Salamanca to evaluate the efficiency and the viability of the system’s implementation. It also features a mobile application for the collection fleet which guides every driver through the best route-previously calculated for each journey. This module dynamically generates routes from data obtained through the deployed nodes to save energy, time and consequently, costs. The platform features a module for optimising waste collection routes. ![]() This monitoring allows the progressive filling data of every town container to be gathered and analysed as well as creating alerts in case of incidence. A prototype of a low consumption wireless node is developed to obtain measurements of the weight, filling volume and temperature of a waste container. ![]() This paper introduces a waste monitoring and management platform used in rural environments. Wireless technologies such as LoRa and low consumption microcontrollers, such as the SAM L21 family make the implementation and deployment of this kind of sensor network possible. ![]() These solutions can also be applied in rural environments, but they require the deployment of a low cost and low consumption sensor network which can be used by different applications. New solutions for managing waste have emerged due to the rise of Smart Cities and the Internet of Things.
