Abstract: Sewer gas is a complex mixture of toxic and nontoxic gases produced and collected in sewage system by the decomposition of organic households or industrial wastes. It includes harmful gases such as oxides of carbon, Sulphur, nitrogen, ammonia and methane. Sewage cleaners are very much affected by these gases. In order to overcome this problem, we are proposing a system which includes integrated sensors for sensing the gases, Arduino UNO and a LCD display to quantify toxic gases which is produced in the system. This system will help to identify the gas level inside the drainage manholes so that the worker can get some idea of entering into the manholes. It helps the workers and provides them safety before getting down into the manholes and it will sense the level of the gas inside. In order to reduce the toxic gases concentration, Sprinkler mechanism is provided with the resource chemical for detoxification treatment. Whenever the gas concentration level exceeds the specified threshold level, an actuator mechanism triggers the sprinkler.
