#raspberry-pi-node-mqtt--esp32 An IoT demo project using ESP32 to send sensor data (humidity, temperature) to a Raspberry Pi via MQTT. Node-RED is used for data visualization and control. Secure ...

This node is responsible for receiving messages from an MQTT broker. It subscribes to a specific topic and receives the published messages. In this setup, the node is labeled "Ottone" and is connected ...

An Arduino Portnta Machine Control arrived at my desk, and like a child, getting a new toy, it's time to play with it a bit. Will this the usual boring lab entry where it works in the end? I guess ...

Abstract: This paper presents a novel approach to home automation utilizing the MQTT protocol. The system is implemented using an ESP32 node and a Node-RED server running on a Raspberry Pi, allowing ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

Abstract: Developments in Internet of Things (IoT) have enabled innovations in smart home and industrial automation, providing possibilities for devices in homes to be monitored and controlled ...

Despite its small form factor, the Raspberry Pi is a highly capable system you can grab for well under $100. Depending on your interests, it can double as anything between an emulation system, stream ...
