Abstract: This paper presents the development of a low-cost, real-time air pollution monitoring system using the Internet of Things (IoT). The system uses an ESP32 microcontroller integrated with air quality, temperature, and humidity sensors to collect environmental data. This data is then transmitted to a cloud platform via the MQTT protocol and visualized using the Blynk mobile application. The proposed system is ideal for monitoring harmful gases in industrial areas and alerting users when air quality deteriorates, contributing to better environmental awareness and occupational safety. Keywords: IoT, ESP32, Air Quality Monitoring, Blynk, MQTT, Sensors, Embedded Systems
