Hi, I can develop a complete industrial pass box controller (Version 2) with reliable interlock logic, HMI integration, and robust automation suitable for cleanroom environments. I have experience in embedded systems and industrial control. I will design a stable controller using ATmega328P (or suggest a more efficient MCU if required), implement fail-safe door interlocking, process sequencing (UV + blower), and integrate the UART-based HMI for configuration and monitoring. The system will be reliable, easy to operate, and ready for real-world deployment. Scope: *Controller PCB design (MCU, relay drivers, power supply) *Firmware development (interlock logic, timers, alarms, modes) *HMI integration (UART communication, parameter setting, display) *HEPA pressure sensor interfacing *Alarm handling and safety logic Deliverables: *Schematic and PCB files *Embedded firmware *HMI communication logic *Documentation Approach: *Implement state-machine based fail-safe control *Ensure strict door interlock safety logic *Accurate pressure monitoring and alarm triggering *Clean and modular firmware for scalability *Validate full system sequence and reliability I will deliver a robust, safe, and industry-ready pass box automation system.

Your pass box requires bulletproof door interlock logic preventing simultaneous opening. I'll engineer the complete industrial PLC/SCADA control system with 7-inch UART HMI touchscreen interface, HEPA differential pressure sensor integration and continuous real-time monitoring, fully automated UV/blower cycling sequences, multi-tone buzzer alarming, complete electrical wiring and panel connections, embedded microcontroller firmware, and full validation testing. ₹10625, 5-day delivery.
