As a four person team, we used four ESP32 devices to create four distinct sensors. They are placed in four places within the general kitchen space on the second floor of AK Watson Hall, designed for future visualization/sonification that pertains to the usage of the space. They are: above the door, on the refridgerator, behind the microwave, and inside a cabinet.

• Cabinet Sensor
  By using a modified button, we are able to detect when a specific cabinet in the kitchen is open, and when it is closed.

• Fridge Sensor
  By transforming the handle of the refridgerator into a giant capacitive touch surface by covering it with aluminum foil and wiring it to an ESP32, we can know when the fridge door is being interacted with.

• Inductor Coil
  By creating an inductor coil wired to an ESP32, we can place it near the microwave's power cord to know when the microwave is being used.

• Door Sensor
  By creating an sensor mounted above the door next to the kitchen with two ultrasonic sensors and an ESP32, we are able to tell when someone either enters or exits the room through the stairwell.

Followed this link to setup a mesh for the ESP32. The dependecies needed are:

• ArduinoJson
• TaskScheduler
• AsyncTCP

ArduinoJSon and TaskScheduler can be found in the Arduino library manager; however, to get AsyncTCP, you have to download the source files and manually add it to the Arduino library.

When using PainlessMesh, each ESP32 has a unique node identifier. By knowing ahead of time which paramaters to receive from each node, we can process those accordingly.

Our simulator script was written in Python (simulator.py), while all the other files were programmed in the Arduino IDE for the ESP32.
