# Problem

There is a problem with the inconvenience associated with maintaining the perfect temperature of beverages. Drinks can cool down quickly, making them no longer enjoyable. The need to reheat a drink can also be time consuming and inconvenient especially with a packed schedule. There is also a problem with waste. Disposable cups and reheating drinks can contribute to waste and negatively impact our environment.
During our research, we found a smart mug called Embur Mug which can detect the temperature of the beverage and keeps it to a desired temperature. However, this mug is way too expensive for people to purchase with a price of 130 dollars.

# Solution

We propose the creation of a smart mug. Our design will improve the Embur Mug functionally and financially. Our mug will be equipped with a temperature control system that will automatically regulate the temperature of its contents to keep the drink at a desirable level. The mug will also have an app interface that will allow users to easily set up their preferred temperature, track their liquid intake and how fast they consume their liquid. The smart mug has the ability to keep drinks at the perfect drinking temperature and will eliminate the need for reheating. The smart mug will also track the amount of liquid in your cup at the moment. We will use a sensor to detect the weight of the liquid and display the number of ounces on your app. The smart mug not only improves the hot beverage drinking experience but also helps promote sustainable habits.



# Solution Components

## Subsystem 1 Temperature Sensor
- Will be integrating the industry standard temperature sensor by Maxim Integrated https://www.digikey.com/en/products/detail/analog-devices-inc.-maxim-integrated/DS18B20%2BT%26R/3478852?utm_adgroup=Sensors%2C%20Transducers&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_Supplier_Maxim%20Integrated_8022_Co-op&utm_term=&utm_content=Sensors%2C%20Transducers&gclid=CjwKCAiAleOeBhBdEiwAfgmXf-hIaZj1YjASEiDZOg5dMMVtSrDlfEeoC1fjx_hQg3LjqtbzHDXz3xoCAXYQAvD_BwE
- Senses the temperature of the liquid

## Subsystem 2 Microcontroller with Wifi transceiver
- ESP8266 SoC board: standard Arduino generic microcontroller with a serial Wifi transceiver to regulate power, control the other subsystems, and send logs to a server that visualizes/analyzes data and handles app notifications.

## Subsystem 3 Warning System
- LED indicating the temperature scale of the beverage (on the mug)
- Send notification to phones if too hot or too cold. (user setting on the apps)

## Subsystems 4 Weight scale system
- Displays the number of ounces of liquid in the mug
- Give notification of refiling via LEDs on the mug

## Subsystems 5 Heating System
- Maintaining the beverage to a desired temperature/healthy temperature.


# Criterion for Success

- Detecting the temperature of the beverage and showing it on the mug via LEDs.
- Tracking drinking habits and visualizing the data on the apps
- Tracking the amount of liquid in the mug and giving refilling notifications via LEDs on the mug.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
