WiFi-Granular Activities in Kitchen Dataset (Wi-GRAK)

A comprehensive dataset containing WiFi channel state information (CSI) and received signal strength (RSSI) data for kitchen activities in different granularities. This dataset contains nine single-person activities, including three fine-grained, three mid-grained, and three coarse-grained activities. We gathered these data for three users and three environments using two ESP32 sensors (transmitter and receiver) and 10 trials for each activity. Therefore, this dataset contains 1620 data entries for kitchen activities.

本数据集为综合型数据集，收录了不同粒度下厨房活动的WiFi信道状态信息（CSI）与接收信号强度（RSSI）数据。该数据集包含9类单人厨房活动，其中细粒度、中粒度与粗粒度活动各3项。本次数据采集采用两台ESP32传感器（分别作为发射端与接收端），面向3名受试者与3种实验环境开展，每项活动均重复进行10次实验。综上，该厨房活动数据集共计包含1620条数据条目。
