Refrigerator and Freezer Monitor

thingiverse

There are two designs included with this make, both feature a waterproof temperature probe and an ambient temperature and humidity sensor. One of them also includes an ambient light meter, but it's tagged as "Garage Refrigerator Monitor." Either design can be used for any purpose, that's how I have them configured. I created a small hole in the door seal of the freezer and refrigerator so I could snake the waterproof temperature probe through the seal without compromising the seal. These devices require no programming if you use ESPEasy.
