About the project

Paean is a health-tech innovator dedicated to building AI-powered solutions for a safe and sanitized society. The company developed AID-3, the world’s first AI-driven commercial decontamination booth, designed to neutralize viruses instantly while ensuring mask detection, social distancing compliance, and temperature screening. Powered by Nvidia Jetsons AI, HD cameras, and DRDO-certified anti-viral technology, AID-3 uses Super-Oxidizing Hypochlorous Acid (HOCL)—a non-toxic, eco-friendly disinfectant that’s 100x more effective than traditional solutions. With a plug-and-play system capable of sanitizing 9000 people per refill, it delivers fast, automated, and intelligent disinfection in just 15 seconds. From corporate offices to public spaces, Paean is redefining health security and intelligent hygiene automation.

BuildBit engineered a revolution in public health tech.

As an operations leader and co-founder of Paean, I needed a partner who could translate our bold vision for pandemic-proof spaces into a robust, scalable solution. When we set out to build AID-3—the world’s first AI-driven decontamination booth—the stakes were high. BuildBit didn’t just meet expectations; they redefined them. Shandhen and the team tackled the complexity of merging Nvidia Jetsons AI with DRDO-certified antiviral systems flawlessly. Their engineers crafted a plug-and-play architecture that delivered 15-second sanitization cycles without compromising safety or user flow. The integration of mask detection, social distancing alerts, and thermal screening wasn’t just innovative—it was life-saving. What stood out was BuildBit’ operational rigor. During trials, they optimized HOCL dispersion to handle 9,000 users per refill while slashing chemical waste by 20%. Their project managers synchronized hardware and software milestones with military precision, ensuring zero delays despite global supply chain hurdles. Today, AID-3 operates in airports, hospitals, and corporate hubs worldwide, and its reliability is a direct result of BuildBit’ expertise. They didn’t just code a product; they built a global health security standard. To the entire BuildBit team: thank you for turning a moonshot idea into a mission-critical reality.

The process 🚧

The development of AID-3 followed a collaborative and iterative approach, bringing together a team of engineers, AI specialists, chemical engineers, and mechanical experts to create a smart, AI-driven decontamination solution. Extensive research was conducted to understand the public health challenges and the need for fast, efficient, and contactless sanitization. By integrating advanced AI algorithms, real-time detection systems, and DRDO-certified chemical engineering, we developed a fully automated decontamination booth capable of mask detection, social distancing compliance, temperature screening, and virus neutralization at a microscale. The mechanical and chemical engineering teams worked closely with our AI and software specialists to ensure precise chemical dispersion, optimal booth design, and seamless system automation. Through continuous refinement based on real-world testing, user feedback, and rigorous safety evaluations, AID-3 evolved into a plug-and-play, high-capacity decontamination booth that is fast, scalable, and environmentally safe. By combining cutting-edge AI, precision engineering, and advanced chemical solutions, Paean is redefining health security and intelligent sanitization for a safer tomorrow.

Stages 🎢
01
Research & Requirement Analysis

Extensive research was conducted to identify public health risks, understand the need for AI-driven decontamination, and develop an effective sanitization solution. Collaboration with chemical and mechanical engineers was key in defining the disinfection process, booth design, and optimal chemical composition.

02
UI/UX Design & System Prototyping

The AI-driven detection system and mechanical structure were designed to ensure seamless user interaction, real-time monitoring, and fast processing. Prototypes were created for mask detection, temperature scanning, and chemical dispersion, with multiple iterations to optimize accuracy and efficiency.

03
AI & Sensor Integration

A Nvidia Jetson-powered AI system was developed to detect masks, enforce social distancing, and measure body temperature in real-time. HD cameras, thermal sensors, and PLC controllers were integrated to ensure precise monitoring and automation.

04
Chemical Engineering & Mechanical Design

The booth’s structure and chemical spraying system were designed for optimal coverage and virus neutralization. A 100L anti-viral chemical tank was implemented to sanitize up to 9000 people per refill, using Super-Oxidizing Hypochlorous Acid (HOCL)—a safe, non-toxic disinfectant.

05
Testing & Performance Optimization

Extensive field and lab testing ensured AI accuracy, chemical efficiency, and overall system reliability. Stress tests were conducted to simulate high foot traffic, various environmental conditions, and emergency scenarios, refining the system for real-world deployment.

06
Deployment & Continuous Improvement

AID-3 was launched as a plug-and-play solution, deployable in corporate offices, public spaces, and high-risk environments. Real-time monitoring, software updates, and ongoing chemical research ensure the system remains scalable, efficient, and future-proof.
