Connecting ESP32 with DS18B20 Sensor and Publishing Data using MQTT Protocol

The Internet of Things (IoT) has revolutionized the way we interact with devices and gather data. One of the most popular microcontrollers for IoT projects is the ESP32, thanks to its built-in Wi-Fi and Bluetooth capabilities. In this article, we’ll explore how to connect an ESP32 to a DS18B20 temperature sensor and publish the temperature data using the MQTT protocol. Components Required ESP32 Development Board: A powerful microcontroller with Wi-Fi and Bluetooth capabilities.

Using Node-RED to Display Data from ESP32 and DS18B20 Sensor

Node-RED is an open-source flow-based development tool for visual programming, originally developed by IBM for wiring together hardware devices, APIs, and online services as part of the Internet of Things. In this article, we will explore how to use Node-RED to display temperature data from an ESP32 microcontroller connected to a DS18B20 temperature sensor. Prerequisites Before we start, ensure you have the following: ESP32 Development Board: A microcontroller with Wi-Fi and Bluetooth capabilities.

Building Simple Applications with Node.js and MQTT

In the evolving world of Internet of Things (IoT) and real-time applications, MQTT (Message Queuing Telemetry Transport) has emerged as a lightweight messaging protocol that’s perfect for small sensors and mobile devices. In this article, we’ll explore how to develop simple Node.js applications that communicate through an MQTT broker. This will give you a basic understanding of both MQTT and Node.js while allowing you to set up a simple messaging system between two applications.

Connecting IKEA TRÅDFRI to an MQTT Broker

As the Internet of Things (IoT) begins to populate our homes with an increasing number of smart devices, many developers and hobbyists look for ways to integrate these devices into a cohesive environment. One such popular device is the IKEA TRÅDFRI lighting system, which offers wireless and user-friendly smart lighting solutions. In this article, I’ll walk you through the steps to connect IKEA TRÅDFRI lights to an MQTT broker, enabling you to control them programmatically and integrate them with other IoT devices.
