Continuing with our Raspberry Pi experiments in today's Wednesday Evening Training

This evening, we continued our labs on MQTT and Node-RED by exchanging temperature and humidity measurements between our Raspberry Pi's. We used Gmail as a message bridge and Bart built a Java MQTT client that we will test in the next session.

To be continued...

Do you want to try yourself? 

Based on measuring with the  DHT11 or DHT22 sensor, a nice place to start reading is https://flows.nodered.org/node/node-red-contrib-dht-sensor. Install this node in your node-RED environment (you might need to download & install the driver), connect it to a timer and debug node and you're off.

Yessss! We've got our own fixed place on the CoZone board! :)
