Hi, I can design and implement your Dynamic Pass Box Controller with robust industrial logic, using ATmega328P or a scalable alternative if needed. I’ll deliver full firmware + schematic/PCB (SMD optimized), covering door interlock safety, blower/UV cycle control, UART communication with DWIN DMG80480T070_01WTR, and HEPA monitoring via MPXV7002DP. The system will include auto/manual modes, alarm handling, parameter control via HMI, and clean modular code for future expansion. I’ll also ensure reliable relay driving, noise filtering, and safety logic validation. You’ll receive tested firmware, PCB files, and a clear documentation/flow guide. Timeline: 5–7 days. Ready to start immediately.

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.
