Hourly Indoor Environmental Monitoring Dataset for a Residential Building in Downtown Mérida

This dataset contains hourly averaged indoor environmental measurements collected using a low-cost sensor network installed in a residential building located in downtown Mérida, Yucatán, Mexico. The monitoring system was designed to record key environmental variables associated with indoor environmental quality and thermal conditions in a tropical warm-humid climate. The dataset provides hourly aggregated observations derived from sensor measurements, enabling the analysis of temporal environmental patterns within a residential indoor environment. The data can support studies related to thermal comfort, indoor environmental quality, building performance, environmental monitoring, and climate-responsive design. Measurements were obtained under real residential conditions in the historic urban centre of Mérida, providing environmental information representative of occupied housing in a warm-humid urban context. The dataset may be useful for researchers, practitioners, and decision-makers interested in sustainable buildings, climate adaptation, and the implementation of low-cost sensing technologies.
