Karachi household water use (daily resolution)

This dataset comes from a study that designed and operated an IoT-aided smart flowmeter system for measuring water use across twenty-three households in the megacity of Karachi, Pakistan. These meters recorded water flow at 30-second intervals, in liters, from October 2021 to May 2023. The installation dates of each individual meter varied based on when the household entered the study. There were also periods of data inactivity due to operational issues, leading to missing data at some nodes for certain time periods. For each household, the time-series of water use was filtered to remove invalid observations including zero (or near zero) flow days or observations beyond the maximum flow that the sensor was rated for. The water use data presented here is aggregated to the daily time step, and divided by the number of household members. The maximum temperature for each day is also provided.

本数据集源自一项研究，该研究设计并运维了物联网（IoT）辅助智能水表系统，用于测量巴基斯坦特大城市卡拉奇的23户家庭的用水量。这些水表以30秒为间隔记录水流量，单位为升，记录时段为2021年10月至2023年5月。每台水表的安装时间因家庭加入研究的时间不同而存在差异。此外，因运维故障曾出现数据静默时段，导致部分时段部分节点存在数据缺失。针对每户家庭的用水量时间序列数据，研究人员进行了滤波处理，以剔除无效观测值，其中包括零（或接近零）流量的日期，以及超出传感器额定最大流量的观测值。本数据集提供的用水量数据已聚合至日度时间步长，并除以家庭常住人口数量。数据集还提供了每日最高气温数据。
