This powerpoint presents an undergraduate thesis on "Design and Construction of a Smart Public Sanitation System". Author: Jimmy Majumder* et al. ABSTRACT: A sanitation technology is ‘smart’ when adapted to local conditions and changing environment. This paper describes the smart health safety public sanitation system to create human behavior by using flash. The system has been constructed based on Artificial Intelligence using the microcontroller series Arduino UNO. Push buttons has been used to operate servo mechanism for door lock operation to lock and unlock the door according to the user interface. This project has been designed with experimental methodology to fulfill the vision of sustainable world from third world countries. A smart dustbin has been used in the system. The dustbin is developed using ultrasonic sensor technology to operate the servomotor. To abate the electricity cost, automatic day light controlled sensor technology is also used. To make the system user friendly an emergency button has been also used for emergency exit. Moreover a water level indicator has been set up to measure the water level inside the flush tank and an alarming system has been also built to monitor the total process of this system. This is a revolutionary invent to ensure the health safety in public sanitation. Keywords: AI, Sanitation, Health safety, Dustbin, Day-night light, Monitoring.

4. The world population is increasing, the safety and health issue is one
of the most alarming sectors. In Bangladesh 60% people are using
public toilet and 5% of them don’t use flush (TheDailyStar). Also in
third world countries; people are not conscious about proper use of
public toilet. As a result, viruses and bacteria get released into the
human body which is responsible for various types of diseases. For
the first time for ever, we have generated an idea to design and
construction of a smart health safety sanitation system for public
sanitation. Thousands of life and billions of dollar will be saved by
proper implementation of the project. 4

Arduino is an open-source, AVR-based electronics
prototyping platform that can be used for a wide
range of projects and is easy-to-use.
A servo motor is a rotary actuator or motor that allows
for a precise control in terms of angular position,
acceleration and velocity.

• Easy to maintain: We established an automated control system.
So, it’s easy to maintain.
• Easy to use:. The system is user friendly to who uses this
sanitation system.
 All-time power supply needed. In the time of load shedding,
backup power is needed.
 Extra cost needed for the awareness program.

24. The mind setup of the user of a public sanitation system is the major
problem to current practice of using flush. For health safety, this
smart health safety sanitation system will introduce a smart
technological and revolutionary invent for human beings to enhance
awareness and habitation in this progressive outcome. For any public
toilet, this invent will also approach consciousness and it will bring
proper sustainability lower cost comparing with others sanitation
system. Nevertheless the truth, Sustainable Sanitation is an
orientation towards behavioural change as it is a progressive step
towards improved sanitation & hygiene practices are an investment
rather than expenditure in the health of future generations.

• Worlds most valuable public toilet till today is undoubtly said
to be sanisatte. It’s cost almost 1crore BDT .
• Eram has a service network across 19 States in India and
fabrication facilities in three States. The basic model of
the toilet costs Rs 2 lack, while the advanced stainless steel
version costs Rs4.5 lakh INR. It’s Almost 5,71500/= BDT
• Smart health safety system needs only 139000/= BDT (Low
cost)
• According to the report on UNDESA. (UNDESA)
• According to the report on The DailyStar . (TheDailyStar)
