Performance of low-cost monitors to assess household air pollution [dataset]

Raw data of PM2.5 and CO from an indoor wood-combustion experiment. We evaluated the performance of two low-cost sensors measuring fine particulate matter (PM2.5) (HAPEX Nano, Climate Solutions Consulting, and TZOA-R Model RD02, MyTZOA) and one measuring carbon monoxide (CO) (EL-USB-CO, Lascar Electronics Ltd.) in a real-world wood-combustion experiment. PM2.5 devices were compared against a DustTrak (Model 8534, TSI Inc.) and a BGI pump (BGI4004, BGI Inc.) and the EL-USB-CO data-logger was compared against a Q-Trak (Model 7575, TSI Inc.). Sampling was conducted in a single-family house in Terrassa (Spain) during five non-consecutive days. All devices were co-located 1 meter away from an indoor fireplace and 0.6 meters above the ground. Fire was set once per day with hardwood logs and kept burning for 12 hours including a minimum of 2 hours with an opened window. The data provided is the raw output from all the devices tested for the 5 sampling days aiming interested researchers to play with the data and reproduce our findings.本数据集包含室内木材燃烧实验产生的PM2.5与一氧化碳（CO）原始观测数据。本研究在真实场景的木材燃烧实验中，评估了两款监测细颗粒物（PM2.5）的低成本传感器（分别为HAPEX Nano，来自Climate Solutions Consulting；以及TZOA-R RD02型，来自MyTZOA）与一款监测一氧化碳的低成本传感器（EL-USB-CO，来自Lascar Electronics Ltd.）的性能表现。其中，PM2.5监测设备以DustTrak 8534型（TSI Inc.）与BGI4004型采样泵（BGI Inc.）作为参比设备；EL-USB-CO数据记录仪则以Q-Trak 7575型（TSI Inc.）作为参比设备。采样工作于西班牙特拉萨市的一栋独栋住宅内开展，共覆盖5个非连续日期。所有测试设备均统一布置在距室内壁炉1米、距地面0.6米的位置。每日点燃一次硬木柴堆，维持燃烧时长12小时，其中至少包含2个开窗时段。本数据集提供了5次采样周期内所有测试设备的原始输出数据，以供有兴趣的研究者开展数据分析与实验结果复现工作。
