This proposal outlines a student research project to develop a portable electronic nose device to detect toxic gases in sewers and manholes. The device aims to protect sanitation workers who frequently encounter health hazards while cleaning. Over 150 deaths of such workers have been reported in recent years. Existing electronic nose devices are often too large or expensive. The proposed prototype would be mobile, using IoT, and affordable. It would reproduce human smell sensing to alert workers to dangerous gas levels and protect their health and safety. A timeline outlines the project plan from funding to testing and production over a 130 day period with a budget of 60,000 rupees.

3. Abstract:
• •Presently, many cases of deaths while cleaning septic tanks have been revealed in India. More
than 150 manual scavenging deaths have been reported in India in the last three years. An
estimated 1.2 million scavengers in the country are involved in the sanitation of our
surroundings. The working conditions of these sanitary workers have remained virtually
unchanged for over a century.
• Apart from the social atrocities that these workers face, they are exposed to certain health
problems by virtue of their occupation. These health hazards include exposure to harmful
gases such as methane and hydrogen sulphide, cardiovascular degeneration, musculoskeletal
disorders, infections, skin problems, and respiratory system problems. This can be prevented
through technology.
• In this study, we have developed a prototype of a handy and low cost portable electronic nose
(E-Nose) for the purpose of sensing toxic, malignant fumes in manholes that lead to the
endangerment of the lives of scavengers working in these inhumane conditions. We aim to
reproduce human senses using sensor arrays and pattern recognition systems so that their
health is not compromised.

5. Market analysis
• Many prototypes of electronic nose have been developed in past years.
Although several commercial E-Nose is available in the market, many of
them are colossal and require a laptop or computer to handle it, which
reduces its portability. On the other hand, several small modern
electronic noses are present for ready use but they are way too
expensive for common man usage.
• In this prototype, we have developed a mobile E-Nose which receives
signals using IoT and thus the need to carry laptops or personal
computers everywhere is demolished. Intended customers include
Department of Drinking Water and Sanitation and some private
organizations.
• What other features can be included in this point? And suggest how
can we deliver product to customers.
