What is the Personal Air Pollution Sensor?
Personal air-pollution sensor is a multi-gas sensing device made for monitoring air quality of a user’s environment. It can accurately detect the presence of Nitrogen Dioxide (NO2), Volatile Organic Compounds (VOCs), and Particulate Matter (PM2.5, PM10). Some of the advanced sensors can also measure temperature and humidity. Sensors are also equipped with LED to notify its user of the current air quality score: Red - "severely polluted," orange - "very polluted," yellow - "polluted," green - "moderate," and blue - "good."
Why is it important?
It is important for us to be aware of air quality and prepare for any preventive method. Severe air pollution has now become a major cause of death and disease globally. Particulate matters are capable of entering lung passage ways and entering the bloodstream causing various cardiovascular and respiratory impacts. The health effects range from lower respiratory infection, lung cancer, chronic obstructive pulmonary disease, heart disease, to increased risk of premature death. Thus, accurate and timely information of air quality around us is a powerful tool to mitigate harmful effects of air pollution.
Students are expected to read a recent news article about air pollution and be able to understand its effect on mortality.
