细颗粒物（PM2.5）和紫外线（UV）等环境污染正在扩大全球公共卫生问题。然而，现有的集中监测站由于时空数据分辨率低，无法正确估计人体接触。无线传感器网络（WSN）使用具有实时能力的仪器，不仅可以提供多种环境因素的细粒度读数，还可以创建污染物的实时映射。在本文中，我们提出了一个无线传感器网络系统，它能够感知多种环境因素，收集数据从多个分散的传感器节点和显示聚合的数据在实时。每个传感器节点都能够探测多种因素，包括温度、湿度、大气压力、PM2.5、紫外线辐射和地理位置。传感器数据传输到服务器，然后通过Wi-Fi网络存储到数据库中。每个传感器节点是便携式的，足以携带个人使用，使我们的系统的广泛的潜在应用。
Environmental contaminations such as fine particulate matter (PM2.5) and ultraviolet (UV) are expanding public health concerns globally. Existing centralized monitoring stations, however, are unable to properly estimate human exposure due to the low resolution spatiotemporal data. Wireless Sensor Network (WSN) uses real-time capable instrumentation could not only provide fine-grained readings of multiple environmental factors, but also create real-time mapping of the contaminants. In this paper we present a WSN system which is capable of sensing multiple environmental factors, collecting data from multiple dispersed sensor nodes and displaying the aggregated data in real-time. Each individual sensor node is capable of probing multiple factors, including temperature, humidity, atmospheric pressure, PM2.5, UV radiation, and geographical location. Sensor data are transmitted to a server, which then be stored into a database through Wi-Fi networks. Each sensor node is portable enough to be carried for personal use, enabling broad potential application of our system.
