Abstract Number: 235 Working Group: Portable and Inexpensive Sensor Technology for Air Quality Monitoring
Abstract There is increasing interest in the deployment of small, lightweight particle exposure monitors that can be worn, or carried in close proximity to a person to obtain a measure the concentration and type of particles they may be inhaling from the environment. Ideally a particle monitor, should be wearable for several days without replacing batteries, and should not interfere with the person’s routine behaviors. It is also important to obtain a measure of the persons ventilation rate. The goal of this presentation is to examine strategies on how the power budget, size and weight of particles monitors can be reduced. The designs of some compact light scattering nephelometers and dust sensors will be compared. A novel particle sensor using fiber optic components will be discussed.
