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 ...

Last time on Minimal MQTT, we used a Raspberry Pi to set up an MQTT broker — the central hub of a home data network. Now it’s time to add some sensor and display nodes and get this thing running. So ...

In this installment of Minimal MQTT, I’m going to cover two loose ends: one on the sensor node side, and one on the MQTT server side. Specifically, I’ll tackle the NodeMCU’s sleep mode to reduce power ...

Understanding how a smart MQTT broker provides ways to aggregate data streams, keep them consistent, and distribute them securely across a complex network to ensure the success of Internet of Things ...

Billions of connected devices need to communicate and move data effectively across networks and cloud platforms. Here’s why MQTT is the standard protocol. The internet of things (IoT) continues to ...

An MQTT client cannot connect through a data diode because MQTT requires two-way data flow just to send data. Before MQTT data can traverse a data diode, it must be received by a broker and converted ...
