Smart Disinfection Tunnel Provides 15-Second Sanitization
4.8
A DIY Smart Disinfection and Sanitation Tunnel project demonstrates a metal-framed chamber that uses a 0.4% sodium hypochlorite mist and PIR-triggered 1HP pump to disinfect people in about 15 seconds. The creator documents hardware, a ~₹30,000 ($400) cost, Arduino relay logic, a 200L tank, 4-way foggers and optional Raspberry Pi counting. It targets public venues like markets, airports, and hospitals.
Key Points
- 1Describes a DIY tunnel that dispenses 0.4% sodium hypochlorite mist to sanitize people in 15 seconds
- 2Explains automated control using PIR sensors, Arduino relay logic, and optional Raspberry Pi for counting
- 3Provides bill of materials, wiring, and code enabling rapid replication for public spaces at roughly $400 cost
Scoring Rationale
Actionable, practical hardware tutorial with clear build details; limited novelty and single-source, unvalidated safety claims restrict impact.
