Vehicles on the road are increasing in number and traffic conditions are getting worse exposing one to a plethora of diseases by going out on the traffic. People do not know the actual measure of the quality of the air they breathe outside on a regular basis, but it is of utmost importance to know of such in order to take precautionary measures. This study sought to make the quality of air known to the general public. Consequently, a microcontroller-centered device which could measure CO, NOx, and C6H6 concentrations in ambient air was developed along with a web application to display and visualize the data. The device uses a fan to sample air into an aluminum pipe containing metal oxide semiconductor gas sensors which detect and measure the gas concentrations in terms of mg/m3. An aluminum steel mesh is installed on the device’s inlet to filter out dust particles and is regularly cleaned by a vibration motor. The web application tabulates and plots data near-real-time whilst presenting the air quality index and a short-term exposure limit warning. Multiple devices can be deployed through registering in the web application. Two three-hour sampling data were gathered at dawn and in the morning along the University of San Carlos – Talamban Campus’ Portal which showed how the pollutant concentrations were low at dawn and which slowly grew higher during the transition to morning when road traffic began. Verification of the device’s readings was done through comparing its results with a private emission testing center’s exhaust gas analyzer. Air quality at the university’s portal was found to be in good condition during the monitoring periods.
