SENTINEL (nsor ework telligent missions ocator) is an application developed in R Shiny to support emerging user groups of lower cost fenceline sensors, such as those monitoring volatile organic compound or methane concentrations inside and near industrial facilities or for emergency response applications. During deployment, sensors collect a large quantity of high-frequency pollutant concentration data, time-aligned meteorological information, and sensor performance indicators. These sensors can collect a quantity of data that is overwhelming for users to process and understand without designated software. The SENTINEL application provides users with a consistent framework for processing, analyzing, and visualizing fenceline sensor data. SENTINEL temporally aggregates data for synthesized analysis and interpretation. Quality assurance screening automatically removes anomalous datapoints and a baseline correction algorithm reduces background drift in pollutant concentration data. SENTINEL offers streamlined sensor data analysis through a user-friendly graphical user interface that supports interpretation of source emission data and sensor-triggered field samples.
哨兵（SENSOR EWORK TELLIGENT MISSIONS OCATOR）是一个用R Shiny开发的应用程序，旨在支持新兴的低成本围栏线传感器用户群体，例如那些监测工业设施内部和附近挥发性有机化合物或甲烷浓度的传感器，或用于应急响应应用的传感器。在部署过程中，传感器会收集大量高频污染物浓度数据、时间对齐的气象信息以及传感器性能指标。这些传感器收集的数据量对于没有指定软件的用户来说多得难以处理和理解。哨兵应用程序为用户提供了一个用于处理、分析和可视化围栏线传感器数据的一致框架。哨兵会对数据进行时间聚合，以进行综合分析和解读。质量保证筛选会自动去除异常数据点，基线校正算法会减少污染物浓度数据中的背景漂移。哨兵通过一个用户友好的图形用户界面提供简化的传感器数据分析，该界面支持对源排放数据和传感器触发的现场样本进行解读。
