"HygiScan is a really smart, practical idea! Making restroom hygiene measurable and transparent with sensors + real-time alerts could transform how public washrooms are maintained and trusted. The focus on users’ health (especially women and…"

"This is a thoughtful and innovative solution to a widespread hygiene problem. Highlighting how HygiScan could be implemented cost-effectively or scaled across different types of public facilities would make the idea even more practical and…"

"This is insane in the best way! Imagine every public restroom being this clean and monitored. But what about power and internet reliability?"

"This is an excellent and socially impactful idea. HygiScan addresses a real and often overlooked public health concern with a smart, data-driven approach. By using sensors to track odor, humidity, and usage, your system ensures transparency in…"

"Bhavana, I’m genuinely amazed! Low-cost, tamper-proof sensors that track restroom hygiene? This is futuristic. How do you prevent vandalism?"

"Bhavana, this could be a game-changer for how we think about hygiene in shared spaces. One question though , how do you make sure cleaning staff actually respond to the alerts? Sometimes the issue is not detection, but action."

"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…"
