Air Pollution Monitoring System Using Waspmote Gases Sensor Board in Wireless Sensor Network

Air pollution poses a significant threat to public health and the environment, necessitating the development of efficient monitoring systems to assess air quality. This project presents an innovative Air Pollution Monitoring System (APMS) designed to measure various atmospheric parameters using some sensors which include mq-135 gas sensor, mq3, mq4 and mq7. The system integrates several key components, including a microcontroller for data processing, a GSM module for remote communication, a buzzer for alerts, a DHT11 sensor for temperature and humidity readings, and an LCD display for local data visualization .The core of the system is some sensors which include MQ135 gas sensor, MQ3, MQ4, and air quality sensor which is capable of detecting common air pollutants such as carbon monoxide (CO), alcohol, and methane (CH4). These sensors provide data, enabling assessment of air quality in the monitored area.

The microcontroller performs data analysis and sends the results to a remote server through the GSM module. Additionally, the system is programmed to trigger the buzzer in the presence of dangerously high pollutant levels, ensuring immediate awareness and response .Local data visualization is facilitated by the LCD display, which provides updates on temperature, humidity, and pollutant levels, allowing users to monitor the air quality on-site. Then uploaded to server.The system also transmits this information to a remote server for further analysis and long-term monitoring.By leveraging the capabilities of some sensors which include MQ135 gas sensor, MQ3, MQ4, MQ7 air quality sensor and the microcontroller, this system contributes to the mitigation of air pollution's detrimental effects and fosters informed decision-making for healthier and more sustainable communities.
