In this project, we intend to provide a system that can detect, monitors and analyze the amount of harmful gases in real time using IOT technology. This project includes a device which has various sensors that detect the toxic gases, water level of the sewage which is placed in the manhole, and a wearable sensing device for the worker. If it reaches the certain threshold level, it sends the information to the authority using GSM and the location to the hospital via GPS.

INTRODUCTION Sewage environment IoT device and IoT platform to monitor poisonous gas has been proposed as a solution to help the sewer workers who put their lives at jeopardy, and ensure minimal health risk. Because of these poisonous gases, the death rate of sewer workers has increased in the recent years. The lack of treatment of sewage after crossing dangerous levels leads to the deaths of thousands of sewage cleaners throughout the year from accidents and various diseases such as hepatitis and typhoid that occur due to sudden or sustained exposure to hazardous gases. Septic tanks are devices which are found commonly in different types of localities, ranging from residential areas to largely developed industrial areas to provide solutions for treatment of sewage wastes. Sewage gases generally arise from the natural decomposition of sewage and their mixtures formed by slurries which leads to the production of toxic wastes that release hazardous gases. These gases can be lethal if inhaled in high concentrations or for a prolonged period of time. Septic tank gases are primarily constituted of methane, subtle traces of carbon dioxide, some parts of Sulphur dioxide, ammonia, hints of hydrogen sulphide (H2S), nitrogen dioxide and traces of carbon monoxide. In order to evaluate the gases which are present in sewage environment, sensors have been used to analyze the amount of hazardous gas and send an alert. The hazardous gases like hydrogen sulphide, methane and carbon monoxide emitted from sewage are sensed by gas sensors every moment and updated when it surpasses the normal grade. The project aims at designing a prototype for monitoring a sewage plant or septic tank in real-time for keeping a check on concentration levels of gases. The designed system can be installed in various sewage facilities, both rural and urban. The system can be made to work properly in both domestic as well as industrial plants, by changing small specifications of design. For remote access of concentration or ppm levels, Thing Speak IoT platform can be accessed from anywhere in the world via internet.
