How to Log Modbus Serial Device Data in SQLite Database using Node-RED

Welcome to this hands-on tutorial where we'll guide you through creating a Modbus Serial Data Logger using Node-RED. We'll show you how to connect an SHT20 Modbus Serial Temperature and Humidity Transmitter to your laptop via an ATC Serial to USB Converter. Then, with Node-RED, we'll read live Modbus Serial data and log it into a SQLite database running locally on your system. This tutorial is your roadmap to building an efficient data logging solution for Modbus Serial devices.

Tutorial Highlights:
📍Hardware Setup: Learn how to connect the SHT20 Modbus Serial Transmitter to your laptop using an ATC Serial to USB Converter.
📍Node-RED Configuration: Get started with Node-RED and configure it to begin building your Modbus Serial Data Logger.
📍Modbus Serial Integration: Discover how to read live Modbus Serial data within Node-RED.
📍SQLite Database Logging: We'll guide you through setting up and configuring an SQLite database to log the data locally.
📍Node-RED Flow: Learn to design a Node-RED flow that efficiently logs Modbus Serial device data into the SQLite database.
📍Testing and Validation: We'll demonstrate how to test the setup and ensure that your Modbus Serial Data Logger is working seamlessly.

Whether you're new to IoT data logging or an experienced enthusiast expanding your skills, this tutorial caters to all levels of expertise. By the end of this video, you'll have a fully functional Modbus Serial Data Logger powered by Node-RED, ready to capture and store data in your local SQLite database.
