After about a year, I swap out my prototype furnace sensor with a permanent solution, complete with 3d printed case and two temperature probes.

I will post a follow-up video once I get some graph data to show the vibration and temperature over a period of time.

In a future video, I will cover in more detail the vibration circuit. It’s a neat circuit and I’ve found a number of great uses for it, including monitoring the washer & dryer cycles.

Here is a link to the tinkercad file, if you want to mess around with the case. I never did add the holes for the back cables.

Products used to make this:

• esp8266
• perfboard
• piezo sensors
• Robo3d printer
