Desenvolvimento de um sistema de monitoramento ambiental com ESP32 e sensores de gás e umidade integrado ao Blynk.

Abstract

Global climate changes and recent events, such as intense wildfires, have increased the frequency and severity of situations that directly affect air quality and human health. Vulnerable populations, such as the elderly, children, and people with respiratory diseases, are the most affected. This highlights the importance of continuous monitoring of air quality and indoor climatic conditions, emphasizing the need for systems that can provide accurate, real-time data for a quick and effective response. This work presents the development of an environmental monitoring system based on the Internet of Things (IoT), whichuses the ESP32 microcontroller, DHT11, and MQ-135 sensors to monitor variables such as temperature, humidity, and air quality in indoor environments. The project aims to contribute to promoting healthier environments, enabling early detection of adverse environmental conditions and facilitating immediate intervention.
