Problem:
public washrooms are an unavoidable part of daily life, especially in schools , hostels, colleges , workplaces , etc. Nevertheless, hygiene is one of the largest issues. Most toilets are either not cleaned regularly or lack transparency about the level of cleanliness. In females, especially, this issue is critical, whereby the lack of hygienic toilets may cause infections like urinary tract infections (UTIs). On my part, there have been instances of fatigue and stress when I do not want to use a restroom during traveling or in hostels due to poor maintenance. This renders the issue to be not only a matter of comfort but also of a public health.
 
Solution:
My solution is HygiScan which is a smart hygiene monitoring device in the public restrooms. The device uses sensors to track :
  • odor levels (ammonia-gas levels/methane-gas levels) to detect foul smell,
  • Humidity sensors to check wet floors or dirty (uncleaned)  floors,
  • usage count sensors to monitor the number of times washroom is used and give out alerts when used heavily.

This information would be calculated and presented as Cleanliness Score on a display touchscreen outside the restroom

  • green = clean,
  • yellow = moderate,
  • red = needs cleaning)

At the same time, cleaning staff would receive real-time alerts on an app, enabling them to clean when needed rather than adhering to a strict timetable.

 
Impact & Benefits:
  • To the users: Guarantees of hygiene, less risk of infection, increased trust in using the common facilities
  • In women and children : protection againts UTI and other health complications.
  • To cleaning staff and authorities: Time saving, cost savings and better accountability.
  • To the society: improved public health and higher hygiene standards.
 
Why it matters to me:
Being a girl, it is incredibly hard to manage in case of unhygienic toilets in the public. The fear of infections and the discomfort of withholding is exhausting. A system like HygiScan would simplify the day-to-day life and make it healthier, safer, and less stressful.

  • I think this could also help during travel—bus stops, train stations, and airports often have terrible washroom conditions. A device like HygiScan would bring much-needed transparency there too.
  • What makes this stand out is the combination of sensors—odor, humidity, and usage count. Together they give a realistic measure of hygiene rather than just relying on visual checks.
  • This idea isn’t just about comfort—it’s about dignity. Everyone deserves access to clean restrooms, and having transparency through a score builds accountability in public facilities
  • The color-coded cleanliness score is simple yet effective. As students, we don’t have time to check details, but a quick red/yellow/green indicator makes decisions easy and quick.
  • I really like the real-time monitoring part. Instead of waiting for fixed cleaning schedules, staff can respond only when necessary—this makes maintenance more efficient and reliable.
  • Your idea for HygiScan is innovative and socially impactful. It addresses a real hygiene problem using smart technology in a practical way. The use of sensors to monitor odor, humidity, and usage is clever and well thought out. To improve it, you could briefly explain how the cleanliness score is calculated and how the system will stay reliable over time. Overall, it’s a smart, empathetic, and meaningful solution that can greatly improve public hygiene and health.
  • This is next-level innovation! I mean, a system that instantly tells you if a restroom is clean or not? Game-changing! But can these low-cost sensors really make it affordable for every school and hostel?
  • This is an innovative and much-needed solution to a widespread public health challenge. The integration of sensors for odor, humidity, and usage count, combined with a clear cleanliness score display, makes HygiScan both practical and user-friendly. By enabling real-time monitoring and alerting cleaning staff efficiently, it not only enhances hygiene standards but also promotes accountability and resource optimization. Most importantly, it addresses the critical health concerns faced by women and children, thereby contributing significantly to improved public health and well-being.
  • Bhavana, this is absolutely mind-blowing! I can’t believe someone has finally thought about real-time cleanliness scoring for public restrooms. HygiScan could literally revolutionize hygiene on campuses and public spaces worldwide. One question though, how will these low-cost sensors stay super-accurate in messy, high-humidity conditions?
  • I never realized how much mental energy I waste worrying about this until I read your post. HygiScan would eliminate a daily micro-stress for me. I hope this becomes a reality!
