Description

Complete SpecificationBACKGROUND OF THE INVENTIONOne of the most challenging task in the recent days is maintaining hygiene in wash rooms .Maintainingcleanliness and hygiene in restrooms is a· critical concern, especially in high-traffic ·areas such as· 5 educational institutions, corporate offices, multinational companies (MNCs), public facilities, and othe>large-scale estab.lishments. Traditional restroom maintenance methods often rely on manual inspectionsand cleaning schedules, which can lead to inconsistent ·hygiene ·levels and delayed response to cleanlinessissues. Such delays may result in unpleasant odors, health hazards, and negative user experiences,particularly in facilities with a high number of daily users.10 In recent' years, the integration of Internet of Things (JoT) technologies has gained traction in the field ofsmart sanitation. loT -based systems offer the ability to monitor environmental parameters in real-time,enabling automated responses to hygiene concerns. However, existing solutions often focus on isolatedaspects of restroom maintenance, such as automatic flushing or basic air freshening, without providing-a' ~ comprehensive system for monitoring and· addressing multiple factors affecting cleanliness and hygiene.IllD..Q) 15 Additionally, water quality plays a significant role in restroom hygiene, especially in tasks such as flushing,1- cleaning, and sanitization. Poor water quality, characterized by high turbidity or improper pH levels, canlead to odors, inefficient cleaning, and ·long-term damage to restroom infrastructure. Similarly, high . ammonia levels or poor.air quality can signal the need for immediate cleaning, yet these factors are often -e""n'" overlooked by conventional systems. There is a need for a holistic smart sanitation solution that combines .....20· multiple sensors, such as turbidity sensors for water clarity, pH sensors for water quality, ana air quality sensors for odor detection, to provide. real-time monitoring and automated maintenance alerts. Such a system should also incorporate features like automatic sanitization, resource-efficient cleaning, and integration with maintenance staff workflows, ensuring that restrooms are kept clean, safe, and hygienic at all times.25 The present invention addresses these .challenges by introducing a Smart Sanitation System withC. Automated Hygiene Monitoring and Maintenance Alerts.Sanitation System that utilizes loT technology to monitor water quality, air quality, and restroom usage, and automate critical tasks such as sanitization andmaintenance alerts. This innovative system ensures high hygiene standards while optimizing resources,making it ideal for large-scale restrooms in diverse settings.The Smart Sanitize system is an advanced hygiene and sanitation management solution that integrates loT5 (Internet of Things), sensor technology, and automation to optimize cleanliness across variousenvironments. Initially designed for restrooms in high-traffic areas, its scope can be extended to healthcare,hospitality, workplaces, public infrastructure, retail, and industrial settings. By leveraging smart automationand real-time monitoring, this system ensures optimal hygiene with minimal human intervention.Beyondrestrooms, Smart Sanitize can be deployed in healthcare facilities to improve hospital hygiene throughI 0 automated patient room sanitation, hand hygiene monitoring for medical staff, and waste disposal tracking.In hospitality and travel, it ensures high cleanliness standards in hotel rooms, airport restrooms, and publictransport vehicles, integrating with existing building mauagement systems (BMS) for seamless operation. ·-~ Educational institutions and workplaces can benefit from AI-driven cleaning schedules, cafeteria hygiene.ll. monitoring, and occupancy-based sanitization. In public infrastructure and smart cities, this technology can power self-cleaning public toilets, citywide air and water quality monitoring, and sanitation solutions ingovernment offices. For. industrial and manufacturing settings, the system can ensure compliance in· cleanrooms, automate industrial wastewater analysis, and maintain sanitation in worker facilities. In retailenvironments, it· can provide real-time restroom cleanliness tracking, self-sanitizing shopping carts, and hygiene feedback displays for customers.Large event venues, stadiums, and entertainment parks canbenefit from smart sanitation solutions that optimize cleaning schedules based on crowd density, trackjanitorial staff hygiene compliance, and ensure continuous monitoring of hygiene levels in high-traffic areas.FIELD OF THE INVENTION:The invention relates to the field of smart .sanitation systems and hygiene management, incorporating ·advanced technologies to monitor, maintain, and improve restroom cleanliness and hygiene standards.5 More specifically, the invention utilizes Internet of Things (loT) technology combined with a network ofsensors, including turbidity and pH sen
