What is an Air Quality Sensor?
An air quality sensor is a device designed to measure and monitor the quality of the air in a particular environment. These sensors detect various components and pollutants present in the air, such as particulate matter, gases, and other airborne contaminants.
Common measurements and data collected by air quality sensors include levels of pollutants like carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), sulfur dioxide (SO2), nitrogen dioxide (NO2), volatile organic compounds (VOCs), particulate matter (PM), temperature, humidity, and more.
Air quality sensors are essential tools for assessing and maintaining the health and safety of indoor and outdoor spaces. They are commonly used in homes, offices, industrial facilities, and urban areas to provide real-time information about air pollution and overall air quality. This data helps individuals, businesses, and governments make informed decisions regarding air purification, ventilation, and environmental policies to ensure the well-being of the people and the environment.
