With the continuous development of information technology, the application level of urban informatization continues to improve. As one of the important representative projects of smart city construction, smart public toilets not only reflect the level of urban management, but also the overall civilization of the city.


Different from traditional public toilets, the key to smart public toilets is intelligence. Smart public toilets combine the Internet of Things, big data, cloud computing, network transmission, sensors and other technologies to enable traditional toilets to have real-time perception, accurate judgment and automatic execution capabilities. Real-time collection of equipment information and environmental parameters through sensors, real-time and effective monitoring and adjustment of the public toilet environment and equipment, realizing the refined management of urban public toilets, and providing high-quality, high-end and comfortable services to citizens and tourists, making the city’s Public toilet management business is more efficient, smart and orderly.


In recent years, the "toilet revolution" has progressed smoothly in various places, but the odor problem of public toilets is still "smelling". The main reason for the odor of public toilets is the hydrogen sulfide and ammonia gas in public toilets. Regarding the concentration of ammonia and hydrogen sulfide, the General Administration of Quality Supervision, Inspection and Quarantine and the Standards Committee have issued relevant odor intensity levels. To reduce the peculiar smell of public toilets, air quality monitoring is essential. Compared with manual supervision, the application of air quality sensors will undoubtedly improve the overall toilet experience.


The special multifunctional air quality sensor for public toilets is a device specially used for environmental monitoring of public toilets. It integrates multiple elements and can monitor eleven environmental elements at the same time. Mainly detect NH3, H2S, temperature, humidity, PM2.5, PM10, atmospheric pressure, light, TVOC, CO2, formaldehyde, O3, CO, CH4, O2, SO2, NO2, H2 and other elements in the public toilet environment. Covers various indicators that reflect air quality. It is installed in public toilets by ceiling or wall-mounted, and continuously monitors the changes of various elements of the public toilet environment. It is a good helper for public toilet environmental monitoring.


Today, smart public toilets have formed a holistic system. The application of multifunctional air quality sensors can provide real data support for public toilet cleaning, ventilation, deodorization, and perfumery decisions.
