How to use Modbus RTU with Arduino, ESP32 & Raspberry Pi Pico to read Sensor Data

𝗩𝗶𝗱𝗲𝗼 𝗗𝗲𝘀𝗰𝗿𝗶𝗽𝘁𝗶𝗼𝗻: In this tutorial, we will explore the Modbus RTU protocol and learn how to implement it with Arduino. Modbus is a communication protocol developed in 1979 for use with programmable logic controllers also known as PLCs. It has become a de facto standard communication protocol in the industry and is now commonly used to connect industrial electronic devices. Modbus RTU which stands for Remote Terminal Unit is a variant of the Modbus protocol that uses binary coding and serial communication to achieve high-speed data transmission. It is widely used in industrial environments for connecting equipment such as sensors, instruments, and actuators to controllers and computers, mainly over RS-485 serial interfaces. We have a humidity temperature sensor that works on Modbus RTU protocol. We will take this sensor as an example and learn in detail about the Modbus RTU protocol. We will write an Arduino code and use an RS-485 transceiver module to retrieve the Modbus sensor data. Apart from Arduino, we will also take a look at some examples of using Modbus RTU with an ESP32 Microcontroller. Later we can write a MicroPython code to implement Modbus RTU Communication with Raspberry Pi Pico. 𝗪𝗿𝗶𝘁𝘁𝗲𝗻 𝗧𝘂𝘁𝗼𝗿𝗶𝗮𝗹 & 𝗚𝘂𝗶𝗱𝗲 1. With Arduino: https://how2electronics.com/how-to-us... 2.
