About this Gig
HELLO THERE!
An HVAC controller is only as reliable as its sensing accuracy, communication interface, and control circuitry. Poor temperature-sensor placement, incorrect RS485 termination, noisy power rails, or improper Modbus RTU timing can cause unstable readings, communication failures, and unreliable heating or cooling control.
I specialize in HVAC controller PCB design, temperature sensing, RS485 communication, Modbus RTU integration, and embedded firmware development.
WHAT I WILL PROVIDE:
- Custom HVAC controller schematic and PCB layout
- Temperature sensor integration and signal conditioning
- RS485 transceiver and communication circuit design
- Modbus RTU protocol and register mapping
- Embedded C/C++ firmware development
- Gerber files, BOM & manufacturing documentation
- Firmware debugging & communication testing
WHY CHOOSE ME?
- Reliable PCB design with practical engineering considerations
- Clean, organized schematics and manufacturing-ready files
- Structured firmware for easier maintenance and expansion
- Focus on stable sensing and dependable Modbus communication
Ready to build your HVAC controller? Message me today to turn your idea into a reliable PCB and Modbus firmware solution!!
FAQ
Can you design a complete HVAC controller PCB from scratch?
Yes! I can design the schematic and PCB layout, integrate temperature sensors, add RS485 communication hardware, and prepare manufacturing files based on your requirements.
Do you support Modbus RTU over RS485?
Yes. I can develop Modbus RTU firmware, configure register mapping, and integrate RS485 transceivers for communication with compatible HVAC and industrial devices.
Which temperature sensors and microcontrollers do you support?
I can work with compatible NTC thermistors, RTD sensors, digital temperature sensors, and microcontrollers such as STM32, ESP32, and other suitable platforms, depending on your specifications.
Will you provide the firmware source code and PCB manufacturing files?
Yes. Depending on your selected package, deliverables can include firmware source code, schematics, PCB layout files, Gerber files, BOM, and technical documentation.
Can you troubleshoot or improve an existing HVAC controller?
Yes. I can review existing schematics, PCB layouts, firmware, temperature-sensing circuits, and Modbus communication issues to identify potential improvements. Please share your files and error details before ordering.
