In the previous two posts in this series, we used Java on the Raspberry Pi mini-computer to send sensor data to HiveMQ Cloud, and visualize it on a dashboard.

• “Part 1: MQTT on Raspberry Pi, Send Sensor Data to HiveMQ Cloud with Java and Pi4J”
• “Part 2: Using MQTT and Raspberry Pi to Visualize Sensor Data on a TilesFX Dashboard”

Now we are going to add some more data to our messaging system with another member of the Raspberry Pi family: the…
