For my project, I decided to measure the temperature of my mini fridge for 24 hours. To do this, I used a thermistor sensor, connected to my ESP32 board with Arduino. I had my laptop sitting outside of the fridge while the cord connected to the ESP32 led from my computer into the fridge. I ended up finding that my mini fridge’s temperature varies by a few degrees (F), and changes quite often. The overall average ended up being 30 degrees Fahrenheit. The minimum ended up being 26.34 degrees. The maximum was 70.61 degrees, this is because I had to start the execution of the code before I could put the sensor into the fridge, so it picked up a few seconds of the room’s temperature. With the numbers that this experiment gave me, I have learned that my fridge actually runs a little bit colder than the average fridge, which according to many different sources, is about 35-38 degrees. My thought for why this is is possibly because there is also a small freezer in the fridge, letting even colder air into the rest of the fridge. Also, the first 40ish minutes or so it looks like the thermistor was still cooling down to the actual temperature of the fridge. The fridge was opened at about the 15 minute mark, which is most likely why it got warmer. After this point, the fridge's temperature fluctuated by a few degrees, but stayed roughly between 26-32 degrees fahrenheit.
