Electrical

The electrical components used in our system consists of the following:

  1. AC/DC Converter
  2. Relay
  3. DC motors
  4. Temperature sensor
  5. Microcontroller (Arduino Uno)
  6. Motor Driver
  7. Breadboard
  8. Jumper wires
  9. 14 AWG wires
  10. Electrical lock
  11. NPN switch
  12. Emergency Stop Button
Software Architecture

The Arduino Uno takes input from the button/switch that’s placed outside the food composter which is then operated by the user. The Arduino Uno will then translate this input, communicate with the temperature sensor inside the heating chamber and decide accordingly.

Our system uses very simple procedure to work. By reading the temperature inside the chamber, the program will determine what needs to be done to achieve the best result of the composting process.
