Design and Implementation of an IoT-based Smart Bio-Toilet with Hygiene Maintaining System

Abstract

This research report focuses on designing and implementing an IoT-based bio-toilet system that prioritizes health, hygiene, and eco-friendliness. This work encompasses deep knowledge of IoT, microcontrollers, bio-toilet systems, engineering design issues, and health and hygiene issues. This is an interconnected sub-system or component having a wide range of applications, including a PV system, sensor systems, microcontroller, structural system, etc. In this smart toilet, a proper hygiene maintenance system has been incorporated. Focus was given to reducing the water consumption in this bio-toilet system. Besides, the method of power generation from biogas and human waste in the toilet system was exploited. Also, an effort was made to produce biofertilizers from human waste. In this work, a method of purifying water by absorbing water from waste was used. In this bio-toilet, extra electricity was provided from solar energy, thus preventing wastage of electricity. The Internet of Things (IoT)-based smart bio-toilet with a hygiene-maintaining system uses IoT cloud monitoring for centralized and remote monitoring, control, and analysis of several bio-toilets together. The simulation was done with the Proteus software, and hardware implementation was done using an Arduino microcontroller. Both simulation results and experimental results are obtained.
