Refresher● Opaque fluid containers are inconvenient to monitor● Lack of precise measuring methods

Concept● Universal retrofit volume measuring platform

○ Home, stadiums, festivals, etc.● Monitor containers

○ Active acoustic sensing to measure volume■ Sweep frequencies to determine change

○ Notifications & container tracking viaweb application

Updates● Prototyping with Raspberry Pi

○ Volume Estimation○ Sweeping Frequencies 600 - 1400 Hz

■ PiGPIO○ Observing resonant frequencies for each container

state● Prototyping web app

○ Basic display○ Minimal dataset

Updates● Volume Estimation

○ Observed resonance at various frequencies and volume levels○ Empty, Half, Full○ 600 - 1400 Hz○ Still working on relating data to fill level

Updates● Porting to cc3200

○ Driving transducer with AudioBoost pack● Custom PCB

○ Stripped down cc3200 breakout board

Final Presentation● Product

○ At least two devices reading different volumes of different containers○ Web application integration○ Calibration for different kinds of containers

● Containers ○ Metal water bottle○ Keg○ Gatorade jug○ Stretch Goal: Observe behavior with propane tanks
