Abstract

This review describes an ongoing effort intended to develop wireless sensor networks for real-time monitoring of airborne targets across a broad area. The goal is to apply the spectrophotometric characteristics of porphyrins and metalloporphyrins in a colorimetric array for detection and discrimination of changes in the chemical composition of environmental air samples. The work includes hardware, software, and firmware design as well as development of algorithms for identification of event occurrence and discrimination of targets. Here, we describe the prototype devices and algorithms related to this effort as well as work directed at selection of indicator arrays for use with the system. Finally, we review the field trials completed with the prototype devices and discuss the outlook for further development.

摘要

本综述描述了一项正在进行的努力，旨在开发用于实时监测大面积范围内空气传播目标的无线传感器网络。目标是在比色阵列中应用卟啉和金属卟啉的分光光度特性，以检测和区分环境空气样本化学成分的变化。这项工作包括硬件、软件和固件设计以及用于识别事件发生和目标区分的算法开发。在这里，我们描述了与这一努力相关的原型设备和算法，以及用于该系统的指示剂阵列选择的工作。最后，我们回顾了使用原型设备完成的现场试验，并讨论了进一步开发的前景。
