What is Smart India Hackathon (SIH) 2026?

Smart India Hackathon (SIH) is the world’s biggest open innovation hackathon organized by the Ministry of Education, AICTE, and MIC, where student teams build hardware and software solutions for problem statements submitted by Government Ministries, Departments, and State Agencies.

How many problem statements are released in SIH 2026?

SIH 2026 features 226 official problem statements, comprising 172 Software category statements and 54 Hardware category statements across themes like Smart Automation, Agriculture, Disaster Management, MedTech, Clean Water, and Cybersecurity.

How does the SIH ONE AI Team Matchmaker work?

The SIH ONE Matchmaker takes your 6-member team’s frontend/backend/AI skills, hardware experience, domain preferences, and exclusions, then runs a multi-factor weighted scoring algorithm to rank the top 25 highest-fit problem statements.

How does the soundbox achieve sub-second payment announcement latency?

It maintains a persistent, lightweight MQTT WebSocket connection over 4G-LTE Cat-1; the moment the bank payment gateway verifies the UPI credit, a compact 16-byte binary payload is pushed to the device, triggering local pre-cached audio phonemes within 650 milliseconds.

How does the dynamic QR display completely eliminate fake payment screenshot fraud?

Static paper QR codes allow fraudsters to show edited fake payment screenshots; our device displays a Dynamic UPI QR code embedding the exact transaction amount and a unique one-time order ID, confirming payment ONLY when the bank server verifies the incoming credit directly on the soundbox screen.

How does the speaker remain audible in noisy street traffic without distorting?

It pairs a 5-Watt high-efficiency Class-D digital amplifier with a custom acoustic ported speaker chamber and dynamic range compression (DRC), delivering clean, distortion-free speech at up to 94 dB sound pressure level.

30-Second Plain English Summary

AICTE Open Innovation: Tertiary Sectors / Hospitality & Retail (Hardware) — Street vendors, small tea stalls, and rural retail merchants across India lose revenue to UPI payment fraud (fake screenshot payment scams), noisy ambient traffic drowning out audio alerts, and high equipment costs of commercial POS billing terminals. Build a Low-Cost Ruggedized Smart IoT UPI Audio Soundbox and Micro-Point-of-Sale Terminal featuring multi-lingual high-volume audio broadcast, dynamic customer-facing UPI QR display, thermal receipt printer, and long-lasting rechargeable battery.
