Honeywell Ultra-Fine Particle Sensor Suite

Abstract

Currently airplanes must bring in fresh air from the outside of the plane and recycle 1:1 with the air already inside of the plane. Reducing the quantity of outside air and purifying recycled air could lead to a one percent savings in fuel consumption which could save airline operators millions in fuel costs. Additional significance of the project comes in the sensor suites analysis of UFP. UFP can present health risks for humans, are absorbed directly into the bloodstream of the lungs, and have been correlated to cabin odor events. This report to Honeywell is to develop an Ultra-Fine Particulate (UFP) Sensor Suite to evaluating air quality for control of aircraft cabin air quality. We will design a sensor package incorporating commercial sensors that detect particulates in the range of 10 to 200 nm (UFP), and to design a package that also contains sensors that measure levels of Volatile Organic Compounds (VOC), carbon dioxide, carbon monoxide, PM2.5 particles and formaldehyde. The sensor suite will also monitor atmospheric pressure, temperature, and humidity of the sensor environment and compensate the data output correspondingly through the use of a Raspberry Pi.
