The system will be equipped in a moving vehicle and consists of a MQ series sensor which detects the foul smell. The sensor is designed to send the information which is a value that indicates the level of toxicity of the smell and location with the help of Global Positioning System fitted in the vehicle. The information will be sent with the support of LoRa (Long Range) network and cloud. The location wise level of toxicity captured in a master screen, would support the authorities in prioritizing the areas to be cleaned up first and would also support in monitoring the results of the action.
