Abstract: - The aim of this study is to address Numerous factors, such as increased vehicle use, urbanization, industry, and population growth, have contributed to rising pollution levels over time. These factors all have an adverse effect on the health of people who are exposed to them, which has a detrimental effect on human well-being. It is recommended to use a wireless sensor network (WSN)-based system to gather and transport data to monitor air quality. The environment's parameters that need to be kept an eye on are temperature, humidity, CO and CO2 volumes, and the presence of any gas leaks (be it LPG, smoke, or alcohol). MQ135 is employed as an air quality pollution sensor, and its output, which is a variable DC voltage, varies in response to air pollution. For instance, higher levels of air pollution result in higher sensor output. The sensor's voltage generates a suitable AQI, which is then shown on the LCD.
