An Inexpensive Data Logger Designed to Record Analog Signals in Hydrogeology and Computer Architecture

该项目测试并集成了一个简单，易于组装且价格低廉的数据记录仪，旨在记录来自现场各种传感器的模拟信号。这个“概念验证”项目建立了数据记录仪的多功能性、可靠性、进动性和准确性，并提供了一些数据记录仪如何融入科学课程的例子。资金用于支付教师工资、本科生暑期帮助和基本设备，包括数据记录仪、各种传感器、各种测试设备和计算机。课程改进主要集中在两个领域，水文地质学和计算机体系结构。在水文学中，数据记录仪收集流域内部和流域之间的流量特征和物质平衡数据。在计算机科学中，数据记录仪用于设计、编程、A/D转换和其他修改。随着时间的推移，数据记录仪是一种廉价的数据收集解决方案，并且与最近兴起的地球系统科学和嵌入式计算机系统很好地集成在一起。跨学科的成果使地球科学专业的学生和计算机科学的同事能够构建特定的传感器和/或修改记录器设计，以检测特定的环境参数。这种廉价的数据记录仪的传播说明和课程改进已在网上公布，在区域和国家会议上提出，并提交给适当的教育刊物。该网站包含数据记录器计划、电路图、电路板布局、零件列表、供应商、用户手册和教程，以便教育工作者（大学或高中）可以下载这些项目并构建自己的数据记录器。该小组已开始计划在项目完成后在全国范围内全面传播和独立测试数据记录器及其课程整合。

This project tests and integrates a simple, easy-to-assemble and inexpensive data logger designed to record analog signals from a wide variety of sensors in the field. This "proof-of-concept" project establishes the versatility, reliability, precession and accuracy of the data logger and provides a number of examples of how the data logger integrates into the science curriculum. Funds cover faculty salaries, undergraduate student summer help, and essential equipment including data loggers, a variety of sensors, various test equipment and computers. The curricular improvements focus on two fields, hydrogeology and computer architecture. In hydrology, data loggers collect flow characteristics within and between stream basins and massbalance data. In computer science, data loggers are used for design, programming, A/D conversions and other modifications. The data logger is an inexpensive solution for data gathering over time and integrates nicely with the recent rise in earth systems science and embedded computer systems. The interdisciplinary results allows geoscience students and computer science colleagues to build specific sensors and/or logger design modifications to detect specific environmental parameters. Dissemination of this inexpensive data logger specifications and curricular improvements are posted on the Web, presented at regional and national meetings, and submitted to appropriate educational journals. The Web site contains data-logger plans, circuit diagrams, circuit board layouts, parts list, suppliers, user manuals, and tutorials so that educators (college or high school) can download these items and construct her/his own data loggers. The team has initiated plans for the complete dissemination and independent testing of the data logger and its curricular integration across the nation at completion of the project.
