Hi, with my experience in Electronics product design field, I can complete your task within given time limit. I had developed a similar device, which was monitor different parameters of Sewage plant. Device was monitoring pressure, water flow and water level using Modbus protocol. I have great experience in electronics product development and firmware development. I have design various types of product, which were based on STM32 microcontroller like GSM based Motor control (2G & 4G), IoT based Data monitoring system (Pressure, water flow & Water level), Water level Controller, Automatic Parking System, Agri Culture Automation, Home Sine Inverter and many other products. I have skills like circuit design, PCB design and firmware development. Looking for opportunity to work on your project. Warm Regards.
