Abstract:
Pollution in industries and urban centers has to be controlled and maintained to recommended
andsafelevels.Withtechnologicaladvancements,variousmethodsshouldbedevisedtoenable
monitoring and control of this levels to the globally safe standards.
Recentlypollutioncontrollevelshasbeenlefttothehandsofthelocalswhoarelargelyrelying on the
traditional methods which give no clue about the quantities detected. As a result, there is a
rising need for support systems that detect and give correct precise values that keeps
awareness among the population. Also with high levels of ignorance and corruption among
various industrial officials, there is also great need for a remote control system that enables

ensure regulation within the safe range which justifies the relevance of the Air Pollution
Monitoring and Alert System.
TheairpollutionmonitoringandalertsystemisanIoTenabledairpollutantdetectionandalert system
for remote monitoring and notification of the industrial staff when pollutant threshold values
are exceed. The system employs a sensor network that reads real time values of the pollutant
gases in the surrounding to trigger alerts when emissions are high. The system also
