Refined Implementation Plan: Smart Pour-Over Kettle

Proposal:

Our proposal is a solution to provide a more comforting morning coffee routine. For example, our smart device will illustrate how integrating moisture and temperature sensors to track the pour-over brewing process will engage the household in a calming yet interactive experience. When the pour-over filter becomes wet, it will notify all household members via. a mobile notification. In addition, a temperature sensor in the carafe will monitor the coffee brew, and upon reaching the ideal sipping temperature, the device will trigger Spotify music throughout the household, playing a selected playlist conducive to enhancing anyone's morning coffee routine.

  A list of the components (aka bill of materials) that will be used:   

A moisture sensor is generally composed of two parts, one is an actual sensing module and the one is a small controller board.

Actual Soil Moisture Sensor: dipped in the soil and does the actual sensing, it is two-wired out the sensor, this out is connected to the sensor control board. Need to connect the 2 header pins (+ and -) to the soil moisture sensor control board as shown by the 2 blue wires above.

Soil Moisture Sensor Control Board: This board takes two-wire inputs from the Soil Moisture Sensor and converts them into digital and analog outputs. It has four pins on the output side pins has 4 pins on the other side labeled VCC, GND, D0, and A0.

Upper-temperature sensor: Typical waterproof temperature sensor. 

Bottom temperature sensor: Attachable temperature sensor. (Looks nice but expensive..)
