AirSniffer: A Smartphone-Based Sensor Module for Personal Micro-Climate Monitoring

Description: Environmental factors can have a significant impact on an individual's health and well-being, and a primary characteristic of environments is air quality. Air sensing equipment is available to the public, but it is often expensive,stationary, or unusable for persons without technical expertise. The goal of this project is to develop an inexpensive and portable sensor module for public use. The system is capable of measuring temperature in Celsius and Fahrenheit, heat index, relative humidity, and carbon dioxide concentration. The sensor module, referred to as the "sniffer," consists of a printed circuit board that interconnects a carbon dioxide sensor, a temperature/humidity sensor, an Arduino microcontroller, and a Bluetooth module. The sniffer is small enough to be worn as a pendant or a belt attachment, and it is rugged enough to consistently collect and transmit data to a user's smartphone throughout their workday. The accompanying smartphone app uses Bluetooth and GPS hardware to collect data and affix samples with a time stamp and GPS coordinates. The accumulated sensor data is saved to a file on the user's phone, which is then examined on a standard computer.

Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement

Description: This report discusses a plan announced by EPA in January 2005, called the Air Compliance Agreement, that would produce air quality monitoring data on animal agriculture emissions from a small number of farms, while at the same time protecting all participants (including farms where no monitoring takes place) through a “safe harbor” from liability under certain provisions of federal environmental laws.

Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement

Description: From an environmental quality standpoint, much of the interest in animal agriculture has focused on impacts on water resources, because animal waste, if not properly managed, can harm water quality through surface runoff, direct discharges, spills, and leaching into soil and groundwater. A more recent issue is the contribution of emissions from animal feeding operations (AFO), enterprises where animals are raised in confinement, to air pollution. AFOs can affect air quality through emissions of gases such as ammonia and hydrogen sulfide, particulate matter, volatile organic compounds, hazardous air pollutants, and odor. These pollutants and compounds have a number of environmental and human health effects. This report reviews key issues associated with the Air Compliance Agreement.

Air Quality: EPA's 2006 Changes to the Particulate Matter (PM) Standard

Description: On October 17, 2006,3 the EPA published its revisions to the National Ambient Air Quality Standards (NAAQS) for particulates to provide protection against potential health effects associated with short- and long-term exposure to particulate matter (including chronic respiratory disease and premature mortality). In order to better understand EPA's actions, this report provides an analysis of the agency's final 2006 revisions to the particulates NAAQS, and the estimated costs and benefits of the new standards and of more stringent alternatives analyzed.
