<br/><br/> Toilet cleanliness is critical for all humans. All germs and bacteria begin their attacks on<br/>the human body here. That is why toilets must be sanitized daily. Foul odors in a restroom<br/>are caused by a lack of cleaning, an unflushed toilet, and a lack of water, while an<br/>adequately cleaned restroom will have no odor issues. Currently, available technologies<br/>and methods can produce exact measurements and effective maintenance and monitoring.<br/>However, these are hand-controlled, expensive to operate, and difficult to monitor due to<br/>insufficient alerting options. As a result, the researchers proposed a restroom maintenance<br/><br/>system that can monitor, notify restroom cleaners, and maintain cleanliness that is IoT-<br/>based with data analytics from the data obtained from air quality sensors and ultrasonic<br/><br/>water level sensors by NodeMCU Wi-Fi Module ESP8266. The system was then assessed<br/>in terms of the indoor air quality of the restroom based on the set time of day by the<br/>researchers. Results show a significant difference in the air quality that can be detected<br/><br/>depending on the time of day, according to the testing results for the hypothesis-way one-<br/>way ANOVA F (5,66) = 164.653, p=.000, and a sample size of n=72. This means that the<br/><br/>system can detect higher concentrations of pollutants in the air, resulting in a foul odor in<br/>the restroom, particularly at 1PM as compared to the other time of the day. The system was<br/>evaluated using the ISO 25010 system and software quality models, and responses from<br/>maintenance staff, university professors, and students yielded an overall mean of 4.8, which<br/>is interpreted as excellent. This project contributes to the United Nations' Sustainable<br/>Development Goals (SDGs) to ensure sustainable consumption and production patterns<br/>(SDG 12), as well as the objective to ensure water availability and sustainable management<br/>for all (SDG 6).
