Treffer: Start using MQTT for sensor logs.

This article from Linux Format discusses how to use MQTT and Node-RED to create a simple sensor system using a Raspberry Pi Pico W. The tutorial explains how to connect a DHT11 temperature and humidity sensor to the Pico W and use MicroPython to write code that reads the sensor data and publishes it to an MQTT broker. The article also provides instructions on setting up Node-RED on a Raspberry Pi to receive and display the sensor data in a dashboard. MQTT is described as a lightweight protocol commonly used in Internet of Things (IoT) projects. [Extracted from the article]
