A Review on Vehicle Pollution Monitoring System

Air pollution remains a pressing global concern, with adverse health effects including chronic obstructive pulmonary disease (COPD) and an elevated risk of cancer. Particularly in metropolitan areas, vehicular emissions, accounting for 70% of total air pollution, pose a significant threat to public health. To address this issue, a research study has been developed to establish an integrated system for monitoring vehicle-related pollution. This system utilizes an Arduino interfaced with a PMS7003 sensor for PM2.5 dust particle measurement, an MQ-7 sensor for carbon monoxide (CO) detection, a NodeMCU for transmitting sensor data to a web server, and incorporates a buzzer and LCD for audio and visual feedback. Its primary goal is to furnish users with real-time air quality information, alerting them to potential health risks. The PMS7003 sensor gauges PM2.5 levels, known for their health implications, while the MQ-7 sensor detects CO emissions from combustion processes. In summary, this integrated system, combining various hardware components, empowers users with comprehensive air quality monitoring capabilities, enabling informed decisions and precautionary measures when air quality deteriorates.
