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.

基于物联网的液化石油气和一氧化碳气体监测系统的设计与实现

如今，液化石油气 (LPG) 的使用有所增加。液化石油气是一种窒息性、挥发性和高度易燃的气体。在液化石油气泄漏情况下，吸入或燃烧气体会增加潜在的健康事故。另一方面，一氧化碳 (CO) 是一种有毒气体，主要来自汽车发动机的燃烧。呼吸一氧化碳污染的空气会导致头晕、昏厥、呼吸困难，有时甚至会导致死亡。为了防止在开放或封闭环境中发生健康事故，包括爆炸，远程实时监测 CO 和 LPG 气体的浓度水平已成为必要。这项工作的目的是展示使用物联网 (IoT) 技术来设计和构建遥测系统，以实时监测周围空气中 GLP 和 CO 气体的浓度。为落实这项工作，作为中央硬件，电子站上有一个微控制器、CO 和 PLG 传感器。此外，亚马逊网络服务（AWS）被用作物联网平台和云中的数据存储。主要结果是一个远程信息处理系统，用于实时监控 GLP 和 CO 气体的浓度，其数据可以通过网站从任何可以访问互联网的设备访问。现场测试取得了成功，并表明所提议的系统是一种高效且低成本的选择。其数据可从任何可通过网站访问互联网的设备访问。现场测试取得了成功，并表明所提议的系统是一种高效且低成本的选择。其数据可从任何可通过网站访问互联网的设备访问。现场测试取得了成功，并表明所提议的系统是一种高效且低成本的选择。
