Recently, I made an IoT temperature probe. It shows data physically over a seven segment display but it can also stream data over WiFi using MQTT.
At first I didn’t really know what I could use it for, but it’s come in handy for MQTT testing. The probe gives me an easy way to start an MQTT publisher. I mean, I could just write a script to do that, but that’s not cool. Besides, hand wiring is fun… right?
