Hardware Design for Multiple Gas Detection System Using Zeolite Coated with Nile Red

摘要

The goal of this research is to develop a nanosensor that integrates a zeolite/dye sensing unit with anoptoelectronic detector, fully integrated into a portable gas sensor. The device will detect and measure more thanone target gas at the same time. Since nanoporous structures of zeolites are manipulated, the device is expected to bemore accurate, more sensitive, is able to better differentiate and detect any one target in a mixture of different gases.This is achieved by incorporating fluorescent dyes into the zeolites’ cavities, measuring gas absorption, desorptionand photo-chromic interaction of dye and gases, interfacing the zeolite/dye sensor arrays with light source andelectronic detectors. The electronic part of the device is fully customized VLSI chip. The final device will bepackaged into a portable unit. The designed and packaged prototype will be presented.
