Indoor and ambient air pollution dataset using a multi-instrument approach and total event monitoring

This dataset comprises 19 subsets. Each subset measures a different parameter or is produced by a different sensor provider. The measurement period for this dataset was from October 11, 2024, to October 31, 2024, and the measurement interval depends on the type of parameter being measured, ranging from 1 second to 15 minutes.

The dataset includes six indoor low-cost sensor providers with their respective measuring sensors. Three of these providers had only one sensor at the location, while one had 16 sensors, and the other two had 4 and 2 sensors, respectively. Human presence was monitored using a camera and a motion detection sensor. Window and door opening and closing were monitored using Xiaomi Door/Window sensors.

In addition to the indoor low-cost sensors, the location was equipped with reference sensing units that were calibrated to the measuring station. Furthermore, outdoor low-cost sensors were also used. Specifically, one was a low-cost sensor, and the other was a mid-range sensor in terms of pricing.

This dataset also includes black carbon data and CPC data. A camera was set up on the balcony to monitor the road in front of the house, so traffic data is also included in the dataset.

Additionally, on-site measuring data from the Croatian Meteorological and Hydrological Service was made available in this dataset, sourced from the two nearest locations to the measuring site, as well as satellite data from the Climate Data Store.

Every single parameter is detailed in the Data.xlsx file, which is integrated into the data.zip archive.

本数据集共包含19个子集，每个子集对应一种不同的测量参数，或由不同的传感器供应商提供。本数据集的测量时段为2024年10月11日至2024年10月31日，测量间隔取决于所测参数的类型，范围为1秒至15分钟不等。

数据集涵盖6家室内低成本传感器供应商及其配套测量传感器。其中3家供应商在该测点仅部署1台传感器，1家部署16台，剩余2家分别部署4台和2台。人员存在状态（Human presence）通过摄像头与运动检测传感器监测，门窗开合状态则采用小米（Xiaomi）门窗传感器完成监测。

除室内低成本传感器外，该测点还配备了经校准的参考传感单元。此外，本次数据集还纳入了室外低成本传感器，其中1款为基础低成本传感器，另1款按定价层级属于中端传感器。

本数据集同时包含黑碳数据与凝聚核计数器（CPC, Condensation Particle Counter）数据。研究人员在阳台部署摄像头以监测住宅前方的道路状况，因此数据集还涵盖交通相关数据。

此外，数据集还提供了来自克罗地亚气象水文局（Croatian Meteorological and Hydrological Service）的现场测量数据，其来源为距离该测点最近的2个站点，同时包含来自气候数据存储库（Climate Data Store）的卫星数据。

所有参数的详细信息均收录于集成在data.zip压缩包内的Data.xlsx文件中。
