Air Quality Monitor Project - Rochester Institute of Technology
Air Quality Monitor Project Jeff Wojtusik Marc Koehler Danielle Howe Matt Knauf Remberto Mendoza Gutierrez Arielle Mizov Project Background Project began Fall 2012 with P13625 Sarah Brownell - Guide
Dr. James Myers Customer Team was charged with building an air quality monitor with increased functionality over previous models. Previous model was created by Berkeley Air Quality monitoring Group in conjunction with University of California Berkeley. Known as UCB-PATS Project Background Cont. The AQM designed by RIT added the increased functionality of detecting CO in addition to
temperature, humidity, and particulate matter(PM). During the build/test phase of MSD there was a lack of appropriate facilities available to calibrate and test the monitor. Air Quality Monitor Motivation In developing countries materials ranging from pressure treated wood, to coal, to feces are burned to both heat and cook within homes. Researchers such as Dr. Myers are gathering data in an attempt to quantify the health effects of these
practices and ultimately use this data to improve the practices and the health within developing countries. Test Chamber Motivation The test chamber motivation comes from the need to be able to accurately calibrate and test the monitors that have been designed and built at RIT. Without calibration and testing the AQM team will not be able to confidently move forward with the current design to the point where the monitor can be used in the field.
Stakeholders Dr. James Myers (Researcher) RITs Associate Provost of International Education and Global Programs Collaborates with RITs global locations, alumni and government partners Investing $500 into project for research Connections to University of California Berkeley (UCB)

Works on improving the test chamber at RIT Air Quality Monitor Project UCB Monitor UCB Particle and Temperature Sensor Records temperature and PM Issues with durability and cost
Cost: $500 Indoor Air Quality Monitor MSD P13625 Measures CO, PM, Temperature and Humidity Cost: $435 Issues with battery life, cost, accuracy Need functioning test chamber to test accuracy of system
Aprovecho Research Center Focused on biomass cooking and heating technologies Indoor Air Pollution (IAP) Monitor Measures CO and PM2.5 Worn as a backpack, measures near mouth of user Cost: $2,400
Goals for Project: Customer Needs Determine which needs are top priority through speaking with stakeholders. Review needs with stakeholders for importance. Goals for Project: Technical
Monitor should have all capabilities of the UCB-PATS monitor Ensure all sensors record continuous data Increase the battery life Improve upon UI Create a monitor which is discrete in subjects home Monitor is capable of resisting outside environment, shipping, and installation Questions for Audience
1. Are our objectives clear? 2. Do you see any issues that a student team may run into while trying to complete these projects? 3. Do you find these projects interesting? What could be done to help increase interest in these projects? Test Chamber Project Stove Test Chamber
Cook stove project is run by Dr. Stevens Burns fuel and collects the PM to be weighed after test. Continually collects CO data via USB CO monitor. Collects data as to weight of fuel burned via a small scale but data must be manually recorded by testers. Does not take continuous data of all metrics. Working towards reducing emissions and improve the efficiency of the stove.
UCB Test Chamber UCB contact: Ajay Pillarisetti (Grad Student) Uses a negative pressure system. The air is sucked through the hood into the chamber. Multiple devices are tested or calibrated at once. Aprovecho Research Center Portable Emission Monitoring System (PEMS) Displays emission levels in real time
Calculates total emissions of CO, CO2 and particulate matter. Test Chamber: Customer Needs The main goal is to develop a testing chamber to detect different levels of particle matter and ability to test sensors. Test Chamber: Goals Exposes monitor to varying level of CO & PM at varying levels of temperature and humidity.
Capable of being moved for storage. Testing levels can be controlled and varied by the user. Test chamber records live data of contaminant concentration in chamber. Safe for users. Questions for Audience 1. Are our objectives clear? 2. Do you see any issues that a student team may run into while trying to complete these
projects? 3. Do you find these projects interesting? What could be done to help increase interest in these projects?
