I am pursuing my master’s degree in Electronics in a distinguished university in Canada with my area of expertise being Analog/Mixed-Signal Circuit design. In 2020, I completed an oven temprature controller using thyristors as switches and an ESP32 Wi-Fi module to communicate with a desktop application which could monitor the temprature and change the PI parameters of the controller; the PCB design was completely in Altium and the coding was done in CodeVision AVR in C. In a nutshell, I believe that project was almost the same as what you want. This is why I believe that I am a great candidate for your project. I am optimistic that we can construct a great collaboration through your project.

Good afternoon Mr, how are you? I worked for 25 years, in a University Institute of Technology, as a professor in subjects such as microprocessors, microcontrollers, PLC automation systems. Please, watch the portfolio in my Freelancer Profile. https://www.freelancer.com/u/R3Acosta. I have created a software that makes it easy to implement graphical interfaces, you do not need to be a programmer to design the interface. In my portfolio you can see a control application in Furnace with heating profile for soldering SMD components. I have designed and manufactured monitoring equipment for Temperatures, Speed, Pressure, and other variables, with modbus protocol, in RS485, through cable or fiber optics, for the oil industry. Embedded systems under Intel Microcontrollers, Microchip and, Arduino platform and C and C ++ languages. I have manufactured a variety of small CNC machines and others for my workshop. I can design the equipment PCB for you. I can design the equipment box for you to be 3D printed. I hope you can contact me to send you more information about it. Best regards.
