Portable VOC-based Live-human Detector for Urban Search and Rescue

This dataset contains development-phase logs used to train and evaluate J48, Random Forest, and a simple probability-level hybrid classifier for a portable volatile-signature detector intended for urban search-and-rescue triage. Data were collected in tethered mode while the ESP32 firmware executed repeating intake–hold–purge cycles. During each hold window the device computed a per-hold feature vector and mirrored it to a host PC along with synchronized raw/derived channels and metadata.本数据集包含用于训练和评估J48、随机森林（Random Forest）以及一款面向城市搜救分诊任务的便携式挥发性特征检测器的简易概率级混合分类器的开发阶段日志。数据采集采用有线连接模式，采集过程中ESP32固件持续运行进气-保压-吹扫循环流程。在每个保压时段内，设备将计算单次保压对应的特征向量，并将该特征向量与同步采集的原始/衍生通道数据及元数据一同镜像传输至主机电脑。
