Feb 5, 2019 · The setting is as follows: I have a pressure sensor from Keller and want to read it digitally via RS485 with the Arduino Mega. The MAX RS485 module is available and connected as shown in the picture. The code I'm currently using is this: int pressure = 0; void setup() { pinMode(19,INPUT); //RX pinM...

In this tutorial, we will discuss how to interface Arduino (as master) to any Modbus RTU (RS485) based sensor (as a slave) using Arduino IDE. We will create an example project by interfacing an RS485 Modbus protocol based energy meter (DDM18SD) using MAX485 (TTL to RS485) module and collect current, voltage, and frequency data from the energy ...

We will use an RS485-based module called MAX485 for communication between two Arduino boards. We will follow the RS-485 master-slave communication method. In this tutorial, we will explain how to communicate between two Arduino boards with the help of the RS485 serial data communication protocol.

RS485 – ARDUINO AND INDUSTRIAL DISTANCE SENSOR: I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications.

Aug 30, 2023 · This is my code to connect and read data from a rs485 sensor. The sensor measure electroconductivity, temperature and salinity, is conected using an MAX485 to ttl converter.

In this tutorial, we'll explore the integration of RS485 (also referred to as RS-485) with the Arduino Nano by utilizing a TTL to RS485 module. This module facilitates the conversion of TTL signals to RS485 signals and vice versa, enabling robust communication over long distances.

Feb 7, 2025 · In this tutorial, we explore the Modbus RTU protocol —a variant of the Modbus communication standard that uses binary coding and serial transmission. We will demonstrate how to implement it with Arduino to read sensor data from a slave device over an RS485 network.

Oct 21, 2024 · Using Arduino with RS-485 modules allows you to create robust communication networks between multiple devices like sensors, actuators, and controllers.
