Abstract
Hygiene in many public toilets, especially in low-income areas, is a major concern due to poor ventilation and lack of maintenance. Governments often invest significant amounts of resources to keep these public toilets hygienic, but these efforts can be futile if there is no central system to monitor hygiene conditions. In many parts of the world, including India, sanitation is not up to the mark, with a lack of clean and ventilated public toilets, leading to health problems. To solve this problem, a low-cost hygiene monitoring device based on air quality standards can be developed. This paper presents the development of an “IoT Enabled Portable Air-Quality Monitoring and Control Device for Public Restrooms/ Toilets”. The device is designed to monitor and regulate the air quality in public toilets up to some extent. The device utilizes the ESP8266 microcontroller and MQ gas sensors to detect the presence of harmful gases, such as ammonia, carbon dioxide, carbon monoxide, methane, etc. along with some other parameters like temperature and humidity. This device also includes an exhaust fan control system to maintain the air quality.
