| dc.description.abstract | This work presents a research on the Internet of Things (IoT) that came to connect things and people currently disconnected. It is the new era in the transformation of existing systems to change the quality of low-cost services to society. In the year of 2013, the fire in the Boate Kiss, in the city of Santa Maria, RS, became the biggest tragedy of this type in the country. Since then, standards and technical instructions have special focus, as well as the study of new instruments that instrumentalize the safety of sites. The work proposes research on an intelligent smoke detector, connected to the internet, explaining the MQTT protocol, the I2C protocol, the ESP32 microcontroller, as well as sensor specifications explain the problem, and propose a simple and low cost solution. This work addresses the study of a system capable of detecting fire and communicating competent bodies through the Internet. The overall objective of the work is to apply a system capable of detecting smoke, different flammable gases and fire through Wi-Fi communication. Therefore, using cheap components and with a simple implementation, it is possible to save lives by acting immediately after the fire starts, the LED on and off by a relay can represent various drives to aid evacuation. | |
