NOTE: Watch the .mp4 video in the repo for a video demonstration of my Sous Vide Cooker

Background: For my final project in my introductor engineering course, Engineering in the Kitchen, I was tasked with modifying, trasnforming, or creating a kitchen appliance. I chose to convert a basic old crock pot that had been in my basement for a long time into a sous vide cooker. I used an ESP32 microcontroller with MicroPython to build my Sous Vide cooker. Users interact with capacitive touch sensors to specify cooking temperatures and times. I also used a Raspberry Pi to run an MQTT broker to interact with a smart plug that powers on/off depending on values sent by the ESP32. The Raspberry Pi also makes it easier to gather cooking data like temperature and timestamps.

Files/Directories: Sous-Vide-Video.mp4: Video demonstration of the machine in use Python Files: SousVide_code.py: The main script for the machine, which is run on the ESP32. Subscribe_and_write.py: This script is run on the Raspberry Pi to catch data sent by the ESP32 and writes it to a csv file. First Steak Analysis: first_steak_analysis.py: This script generates graphs of the data from the first steak I cooked first_steak_graph.png: graph of temperature vs time for the first steak I cooked (note that the desired cooking temperature was 55) graph_with_power.png: The same as the previously listed graph, but also has vertical lines indicating when the machine was turned on/off to maintain temperature Two .csv files containing data from the first steak I cooked
