Precision Automatic Titration System (PATS)

Maker Faire Bay Area 2025

September 26th-28th

Arduino

PATS brings to life an autonomous system capable of titrating chemicals with micro-liter engine movements by integrating high accuracy mechanical structures and electronics. Our system is a solution to the problems faced by traditional manual titrations, such as results that are less accurate, less precise, and prone to human error. Mastering chemistry, Arduino boards, pH sensing technology, and 3D printing designs allowed us to create an autonomous and consistent method of titration. Utilizing an LCD display, PATS can also display real-time data on temperature and pH reading to the user.

Our project is motivated by the Flint Water Crisis where titration played a vital part in detecting lead in residents' drinking water. But beyond water safety, PATS has extensive applications in agriculture, food safety, healthcare, even the automobile industry, and much more.

Key Components:

- Precise stepper motor movements for injection of reagent (0.66 micro-liters per movement step)
- Custom
