A WEB APPLICATION FOR MONITORING AND ALERT OF HIGH TEMPERATURES, LPG GAS AND SMOKE FROM A RESIDENCE

Abstract

Currently, the vast majority of gas and smoke detection sensors available on the market are efficient only when there are people in the house, and this ends up being a great barrier, since people need to leave the house to work or to deal with personal interests. This article sought to develop a web application based on the Internet of Things (IoT), in order to ensure greater prevention against residential fires, through remote monitoring of temperature, LPG gas and smoke, as well as the issuance of alerts by WhatsApp messages. For this purpose, the Java programming language (version 11) was used with Spring Framework modules, along with the NodeMCU development board and sensors for Arduino. Furthermore, during alerts, high temperatures and gas and smoke detections are recorded in a database, with the date and time of the event. Thus allowing the user to have access to the detection history of each month. The tests performed on a mockup were quite satisfactory, and the web application demonstrated effectiveness in both monitoring and alerts.
