TOILET

With increased urbanization and the growing need for better sanitation hygiene practices across several countries, including many developing nations such as Nigeria, there was a great need for better sanitary facilities that would allow for cleaner sanitation. Most conventional latrines have required high manual intervention and constant maintenance, creating an environment that is often dirty, wastes water, and does not have enough cleaning facilities, even in places like restrooms at homes and public places. Despite some innovative restrooms being designed before, the majority of such restrooms either lack feasibility financially or do not contribute effectively to smart hygiene monitoring. The smart toilet design mentioned in this paper seeks to overcome the above challenges. The proposed system comprises User Detection using Sensors, automatic Flushing, Optimization of Water Usage, Surface Hygiene monitoring, with Logic implemented using a microprocessor, and Wireless Communication as well. The design employs Infrared and Proximity Sensors for detecting the presence of the user and seat usage. The system utilizes solenoid valves for controlling the amount of water used in flushing. Furthermore, the proposed system will incorporate Adaptive Flushing Logic whereby the amount of water will be optimized to improve its usage and conserve more water. Testing will be done to evaluate the performance and ensure the proper functioning of the sensors and accuracy of the flushing. After completion of the project, the expected outcome would be a working smart toilet with automatic flush capability. Moreover, after testing it is expected that the system will be capable of reliably detecting users and communicating wirelessly while optimizing water usage as well as ensuring restroom hygiene. Not only is the project useful for home and public usage but also it will go a long way to improving the sanitation level in the ever-growing cities.

The unending evolution of technology has led to innovations in everyday facilities, and restroom infrastructure isn’t left out. This project focuses on the DESIGN AND IMPLEMENTATION OF AN AUTOMATED TOILET for the Mechanical Engineering Department of the University of Benin. This automated toilet integrates automation, hygiene, and efficiency-enhancing features to improve user experience, environmental sustainability, and operational convenience.
The system incorporates a limit switch which sends signal to the modified autoflush device whenever a user opens the door, contactless flushing, odor detection, water efficiency mechanisms, enhanced hygiene protocols and a automated lock which incorporates both biometrics and a card reader to enforce access control. The design process involved conceptualization, material selection, fabrication, and performance testing. All ensuring optimal functionality in the university environment. The Testing results indicated that the automated toilet performed efficiently, with responsive automation and reliable hygiene features being implemented to foster a contactless user experience. The implementation of this system demonstrates the potential of automated restroom solutions in the enhancement of sanitation, water wastage, while also providing a modern, user-friendly facility. Some future improvements could include ultrasonic sensors for higher precision, improved water conservation strategies, and also more compact design elements. This project highlights the role of automated technology and modification in modern sanitation and its potential for broader applications in both public and private facilities.
