# 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.

Problem:

The Donor Wall on the southwest side of first floor in ECEB is to celebrate and appreciate everyone who helped and donated for ECEB.

However, because of poor lighting and color contrast between the copper and the wall behind, donor names are not noticed as much as they should, especially after sunset.

Solution Overview:

Here is the image of the Donor Wall:

http://buildingcampaign.ece.illinois.edu/files/2014/10/touched-up-Donor-wall-by-kurt-bielema.jpg

We are going to design and implement a dynamic and interactive illuminating system for the Donor Wall by installing LEDs on the background. LEDs can be placed behind the names to softly illuminate each name. LEDs can also fill in the transparent gaps in the “circuit board” to allow for interaction and dynamic animation.

And our project’s system would contain 2 basic modes:

Default mode: When there is nobody near the Donor Wall, the names are softly illuminated from the back of each name block.

Moving mode: When sensors detect any stimulation such as a person walking nearby, the LEDs are controlled to animate “current” or “pulses” flowing through the “circuit board” into name boards.

Depending on the progress of our project, we have some additional modes:

Pressing mode: When someone is physically pressing on a name block, detected by pressure sensors, the LEDs are controlled to

animate scattering of outgoing light, just as if a wave or light is emitted from that name block.

Solution Components:

Sensor Subsystem:

IR sensors (PIR modules or IR LEDs with phototransistor) or ultrasonic sensors to detect presence and proximity of people in front of the Donor Wall.

Pressure sensors to detect if someone is pressing on a block.

Lighting Subsystem:

A lot of LEDs is needed to be installed on the PCBs to be our lighting subsystem. These are hidden as much as possible so that people focus on the names instead of the LEDs.

Controlling Subsystem:

The main part of the system is the controlling unit. We plan to use a microprocessor to process the signal from those sensors and send signal to LEDs. And because the system has different modes, switching between them correctly is also important for the project.

Power Subsystem:

AC (Wall outlet; 120V, 60Hz) to DC (acceptable DC voltage and current applicable for our circuit design) power adapter or possible AC-DC converter circuit

Criterion for success:

Whole system should work correctly in each mode and switch between different modes correctly. The names should be highlighted in a comfortable and aesthetically pleasing way. Our project is acceptable for senior design because it contains both hardware and software parts dealing with signal processing, power, control, and circuit design with sensors.
