This project develops an IoT-based system to continuously monitor noise and air pollution in urban, industrial, and residential areas in a cost-effective and reliable way. The system utilizes an ESP32 microcontroller integrated with a sound sensor and MQ135 gas sensor to measure ambient noise levels and air quality parameters in real time. The collected data is processed and compared with predefined safety thresholds, displayed locally on an LCD, and transmitted to a cloud-based dashboard via Wi-Fi for remote monitoring. An alert mechanism using a buzzer is activated whenever pollution levels exceed safe limits, ensuring immediate awareness and timely response. Owing to its low cost, scalability, real-time monitoring capability, and remote accessibility, the proposed system supports smart city initiatives, environmental protection, and public health management.
