The contamination has a major role in weaken air system. Every vehicle has its own emission of gases, but the problem occurs when the emission is beyond the standardized values. This emission from vehicles cannot be completely avoid, but it definitely can be control. The proposed system concept is based on wireless sensor network and Internet of Things. It includes in two separate parts. One is transmitter/ordinary node and another is master/sink node. The transmitter node is consist of DHT11, CO, Ionization, LPG sensor and nRF24 module with atMega328p microcontroller. The transmitter node will be attach with vehicle, CO sensor placed at outlet of smoke, LPG and DHT11 sensor has placed nearby fuel tank. And the master node has consist of nRF24 module and Raspberry pi board. The master node has placed at the traffic signals and more zones in the city. The transmitter node reads the values of the sensors and transmits nearest it to master node using Radio Frequency. The master node is connected with cloud using Wi-Fi or Ethernet and it create, update and store contamination history in the database as well as user dashboard. When the emission level or Ionization level or gas leakage outreach threshold value then cloud server will send the alert notification for maintenance to vehicle owner via SMS of email. On the basis of city wise contamination history, a strict action can be taken by administration to reduce the contamination from last year of contamination history. The proposed novel system helps reduce and store contamination history.
