| # TipsyTracker # Team Members: - Akash Patel (ayp2) - Sumedh Vemuganti (sumedh2) - Eshrit Tiwary (etiwary2) # Problem Irresponsible drinking is a widespread problem, especially among university students. Unfortunately, many people often lose control of their alcohol consumption simply due to a lack of awareness of how much they have consumed. To combat this issue, we propose to create TipsyTracker , a system that promotes responsible drinking. The system will remind partygoers to periodically check their blood alcohol content (BAC) levels and alert the host if a guest's BAC level exceeds a certain limit. This way, partygoers can stay informed of their alcohol consumption and make more informed decisions, while the host can ensure that the party remains safe and enjoyable for everyone involved. By implementing this system, we hope to create a more responsible and enjoyable party experience for all. # Solution TipsyTracker will revolve around a device that uses a breathalyzer to measure the blood alcohol content (BAC) levels of partygoers. Upon arrival, guests will be given an RFID-enabled wristband/card which will be scanned by the device's built-in RFID reader when they initiate a breath test. The device is powered by an ESP32 microcontroller and is connected to a Raspberry Pi, which acts as a server. Once a partygoer initiates a test, the microcontroller will send the RFID and breathalyzer data to the Pi. The Pi hosts the necessary software and databases, handles communication between the device and registration station, and sends notifications to guests and the host. Guests will receive notifications at set intervals to test their BAC levels, and if they fail to do so within a set limit, the host will be notified. Additionally, if a guest's BAC level exceeds a certain threshold, the host will also be notified. The goal of this project is to promote responsible drinking at social gatherings and make them more enjoyable and safer for everyone. # Solution Components ## Subsystem 1 (RFID Identification Subsystem) - on PCB This subsystem will be responsible for identifying each partygoer or patron by reading their RFID-enabled wristband/card when they initiate a breath test. This subsystem will be connected to the ESP32 microcontroller which will wirelessly send this data to the Raspberry Pi, which correlates an RFID to a user’s name and phone number. Subsystem 1 Modules: MFRC522 RFID: https://www.amazon.com/SunFounder-Mifare-Reader-Arduino-Raspberry/dp/B07KGBJ9VG ESP32-WROOM: https://www.amazon.com/ESP-WROOM-32-Development-Microcontroller-Integrated-Compatible/dp/B08D5ZD528/ref=sr_1_5?crid=395FTKAFRGYNK&keywords=ESP32-WROOM&qid=1674683343&s=electronics&sprefix=esp32-wroom%2Celectronics%2C120&sr=1-5&th=1 ## Subsystem 2 (Breathalyzer measurement subsystem) - on PCB This subsystem will be responsible for measuring the BAC levels of the partygoers/patrons by using a breathalyzer. It will be connected to the ESP32 microcontroller and will communicate with the RFID identification subsystem to ensure that the test results are associated with the correct partygoer/patron. A light will turn green when the device is ready for a partygoer to test their BAC. This subsystem will be connected to the ESP32 microcontroller, which will send the data to the Raspberry Pi. Subsystem 2 Modules: MQ-3 sensor: https://www.amazon.com/Alcohol-Detector-Ethanol-Detection-Raspberry/dp/B09HY1H6VW/ref=sr_1_2?crid=2FOU5M2NX4THQ&keywords=MQ-3+sensor&qid=1674682965&s=electronics&sprefix=mq-3+sensor%2Celectronics%2C106&sr=1-2 ESP32-WROOM: (same as subsystem 1) Green LED: https://www.amazon.com/MCIGICM-Circuit-Assorted-Science-Experiment/dp/B07PG84V17/ref=sr_1_1?crid=ZEO8CF2AHP8P&keywords=led+circuit&qid=1674685556&sprefix=led+circui%2Caps%2C114&sr=8-1 ## Subsystem 3 (Notification and data management subsystem) - off PCB This subsystem will be responsible for handling the communication between the device and the registration station, as well as sending notifications to partygoers/patrons and the host. It will be powered by a Raspberry Pi server, which will host the necessary software and databases, and will handle data storage, analysis and management of the entire system. It will also send notifications to partygoers/patrons at set intervals to remind them to test their BAC levels, and notify the host. Subsystem 3 Modules: Raspberry Pi: https://www.raspberrypi.com/products/raspberry-pi-4-model-b/ # Criterion For Success The following high-level goals will be needed for our project to be effective: 1. Accurate measurement of BAC levels: The device should be able to accurately measure the BAC levels of partygoers. This can be tested by comparing the results of the device with those of a calibrated breathalyzer. 2. Effective RFID scanning: The device should be able to scan and store the data of guests' RFID-enabled wristbands/cards efficiently, with no errors in data storage or retrieval. This can be tested by placing a colored sticker on each RFID card, scanning various RFID cards in rapid succession, and ensuring that the color and the RFID number match. 3. Accurate notifications: Messages to partygoers and the host should be accurately sent. This can be tested by monitoring notifications. We can test by timing notifications, and ensuring they are being sent at correct intervals. 4. Updated interface:The Web-interface should reflect updates to party goers who test their BAC levels. This can be tested by conducting many user tests and seeing if the page updates accurately. |
