I will develop plc to PC communication with modbus tcp and python

Need your ESP32 or Arduino project to actually work? I'll write clean, reliable firmware for your sensors, actuators and IoT monitoring.

I'm an automation engineer who integrates PLCs, robots and sensors every day, and I've built ESP32/Arduino monitoring systems with MQTT and mobile dashboards.

What I can do:

- Read sensors: temperature, humidity, pH, distance, current, and more

- Control relays, motors, pumps, LEDs and displays

- Wi-Fi and MQTT communication for real-time monitoring

- Sensor calibration, filtering and data logging

- Fix or improve your existing code

What you get:

- Well-commented source code (Arduino IDE or PlatformIO)

- Wiring guide for your modules

- Revisions according to your package

How testing works: I test the code in a simulator (Wokwi) or with common modules on my bench. You run the final test on your hardware, and I support you until it works.

Please message me before ordering with your board, modules and what the project should do, so I can recommend the right package.
