    Nowadays use of liquefied petroleum gas (LPG) has increased. LPG is an asphyxiating, volatile and highly flammable gas. In a LPG leak situation, potential health accidents are increased either by inhalation or by combustion of the gas. On the other hand, carbon monoxide (CO) is a toxic gas that comes mainly from combustion in car engines. Breathing CO-polluted air can cause dizziness, fainting, breathing problems, and sometimes death. To prevent health accidents, including explosions, in open or closed environments, remote and real-time monitoring of the concentration levels of CO and LPG gases has become a necessity. The aim of this work is to demonstrate the use of Internet of Things (IoT) techniques to design and build a telemetry system to monitor in real-time the concentration of GLP and CO gases in the surrounding air. To implement this work, as central hardware there is a microcontroller, CO and PLG sensors on the electronic station. Besides, Amazon Web Services (AWS) was used as an IoT platform and data storage in the cloud. The main result was a telematics system to monitor in real time the concentrations of both GLP and CO gases, whose data is accessible from any device with internet access through a website. Field tests have been successful and have shown that the proposed system is an efficient and low-cost option. Comment: David C. Wyld et al. (Eds): BIoT, DKMP, CCSEA, EMSA - 2021 pp. 31-39, 2021.

    This paper presents how the COVID-19 pandemic has changed the course of the mobile robotics market, showing the status of mobile robots in three stages: before, during and after the COVID-19 pandemic. By analyzing these stages, it is possible to estimate what awaits this market in the future. From the many applications of mobile robots found during the COVID- 19 pandemic, as will be shown later, it is clear that mobile robots will be an important part of the future influencing the accelerated growth of their market and development.

    This paper describes the design and functioning by stages that compose the environmental and electric parameter recollecting device for research Purposes, energetic efficiency, that take place in the production of electric energy using a photovoltaic panel. The device has a local storage through an uSD memory card and remote cloud storage. The device is classified as an IoT device. The information can be accessed through a mobile app. It has temperature, UV rays, light, current, voltage and power sensors. A prototype of the device has been constructed and the results of this prototype are shown in a display and the electric variables were compared using a calibrated multimeter.

    The use of SCADA systems in modern industrial processes represents a high cost to the industrial sector due to licensing payments, difficulty in connecting to RTUs from different manufacturers, support only for industrial communication protocols and limited scalability when using a structured database. In this work, a low cost SCADA system was developed, with the possibility of connecting to an RTU based on IoT technology that makes universal communication with field devices through TCP / IP and supported on a NoSQL database. We also evaluate its functionality on a traffic management process incorporating as semaphore field device, which demonstrates the versatility of the solution with response times comparable to those of any commercial alternative.
