Dear Client,\n\nI understand this is a safety-critical EVT hardware design for a Smart LPG Gas Monitoring & Safety Device for Nepal, targeting EN 50194 and mass production. The project demands reliable LPG leak detection (MQ-6 or equivalent), cylinder low/empty detection, local buzzer and LED indicators, an ESP32 controller with offline operation, optional 12V solenoid valve drive, and fail-safe behavior including power switchover and keeping gas open on total power loss. My approach is to deliver a clean, manufacturable EVT package in four phases: architecture & safety design (power tree, backup duration, BMS, isolation concept), schematic design with robust analog front-end and fault logic, PCB layout focused on EMI and manufacturability, and EVT support including bring-up, calibration, and final report with DVT readiness. Deliverables include PDF architecture diagrams, BOM, complete schematics, Gerbers, test plans, and an EVT-ready package with IP owned by you. What gas sensor options do you prefer (MQ-6 or equivalent) and what sensitivity and response time targets should we meet?\n\nWhat backup runtime do you require with 2x18650 packs and BMS, and are there size/weight limits?\n\nWhat isolation/EMI specs and regulatory constraints beyond EN 50194 should we plan for, especially Nepal regulations?\n\nShould the device operate fully offline or allow optional remote updates/monitoring?\n\nDo you have specifics for the solenoid valve drive (voltage/current, isolation, latchin

Hello, how are you? This is a safety-critical EVT hardware program, not an experimental prototype. I am proposing a complete, certification-oriented hardware design package built from day one for reliability, fail-safe behavior, and manufacturability. I will deliver a full EVT-ready system architecture for a Smart LPG Gas Monitoring & Safety Device, including power-loss-safe design philosophy (gas remains OPEN on total power failure), seamless 12V mains → dual-18650 battery switchover, and isolation-aware solenoid valve control. All design decisions will be documented with clear safety assumptions and risk mitigation notes, aligned with future EN 50194 certification pathways. Scope covers: • System architecture, power tree, and safety analysis • Full schematics with cost-aware, available components • Low-noise analog front-end for gas sensing • EVT-grade PCB layout with EMI, creepage, and testability in mind • EVT bring-up guidance, calibration procedure, and one refinement cycle You will receive manufacturer-ready files (schematics, PCB, Gerbers, BOM, assembly notes) suitable for fabricating 2–5 EVT units and transitioning cleanly into DVT. My focus is not “making it work,” but making it safe, auditable, and ready for mass production. If you need an engineer who understands that gas safety hardware has zero tolerance for ambiguity, this project is an exact match. Best regards, Yilin.
