[Vegard Paulsen] created a solder iron that reports its usage and temperature to ThingSpeak and alerts him when it was left on. He uses an NodeMCU / ESP8266 Wi-Fi module to collect the data and post it to his ThingSpeak channel. Once the data is on ThingSpeak, he is able to send push notifications to his phone using the ThingSpeak React App.
Hackaday.com wrote an article about Vegard’s soldering iron connected to the Internet of Things. Here’s what they had to say:
The data pushes out to the ThingSpeak server which handles pushing data out to the bigger network, and data representation (like the cool Google gauge…). The best part: [Vegard] gets a phone notification when he accidentally leaves his soldering iron on. How perfect is that?
That looks a lot like our desks… wires, microcontrollers, pliers, cutters, Wi-Fi modules, and soldering irons. And now, the soldering iron is on the Internet of Things.
