Occupancy detection in a student room

In order to compare the performance increase in occupancy detection by adding one sensor, a room was outfitted with a motion, temperature, carbon dioxide, light, and a humidity sensor. Opening and closing of the door is monitored, as well as the connection of the smartphone of the occupant with the local WiFi network. Finally, the distance to home of the smartphone of the occupant was also logged in 5 minute intervals. A ground truth was collected using the input of the occupant.

为对比添加单传感器后人员占用检测（Occupancy Detection）的性能提升幅度，本研究在一间实验房间内部署了运动传感器、温度传感器、二氧化碳传感器、光照传感器与湿度传感器。同时监测房门的开合状态，以及该住户的智能手机与本地WiFi网络的连接情况；此外，还以5分钟为时间间隔，记录该住户智能手机与家庭住址的距离数据。研究人员通过住户的手动输入信息采集了真实标签（Ground Truth）。
