How to interface ESP32 with RS485 (Modbus) sensors with example code

📘 If you want to understand how real embedded systems are designed beyond tutorials, I’ve put together a short practical guide based on my 7+ years of real project experience. 👉 50% launch offer available for the first 100 copies: https://hasaneee.gumroad.com/l/embedded-system-product-from-zero In this video, we showed how we can interface ESP32 to any RS485 Modbus RTU based sensors using Arduino IDE. We created an example project by interfacing an RS485 Modbus protocol-based energy meter (DDM18SD) using MAX485 (TTL to RS485) IC and collecting current, voltage, and frequency data from the energy meter.
