Research question and field context

This first-author conference paper examines what it takes to collect dependable indoor-air-quality evidence in low-income Philadelphia households. The study treats residential sensing as socio-technical fieldwork: monitor selection, placement, connectivity, privacy, trust, scheduling, and community partnerships all shape what data can be collected and interpreted.

Awair Element and IQAir AirVisual Pro monitors were prepared and compared for residential deployment.

Priority before deployment

Plan for offline data continuity.

Connectivity is the current bottleneck. Add local buffering, visible device-status checks, and a recovery plan before relying on remote transfer.

Mixed-methods field design

The project combined Awair Element and IQAir AirVisual Pro monitoring with participant communication, field observation, qualitative assessment, and collaboration among Drexel researchers, the Philadelphia Energy Authority, the Energy Coordinating Agency, Esperanza, and household members. The methodology linked technological solutions, data-collection logistics, and community collaboration from the start.

The mixed-methods design coordinates technology, field logistics, and community collaboration.

What field deployment revealed

The program began with 54 targeted households. Sensors were installed in 11 homes, and five installations yielded usable data. This progression became a central research result: more than half of the potential locations lacked stable usable Wi-Fi, while privacy concerns, participation, coordination, monitor placement, building conditions, and equipment limitations further shaped deployment and retrieval.

The published paper compares the two monitoring platforms across calibration, placement, parameter coverage, access, and usability.

Four-part challenge framework

Qualitative analysis organized the field experience into four connected domains: participants, collaborators, technical challenges, and logistics. Awareness, privacy, and ownership influenced participation; stakeholder coordination shaped access; sensor and building constraints affected data quality; and communication, scheduling, infrastructure, and funding determined whether the study could operate consistently.

The challenge framework makes the social and technical dependencies of occupied-housing research visible.

Recommendations for stronger field studies

The published work translates those obstacles into an implementation agenda: targeted participant education, clear privacy protocols, durable community partnerships, flexible coordination, improved sensing and connectivity strategies, adequate funding, and a comprehensive field plan that integrates technical and social requirements.

Seven recommendations connect participant trust, technical infrastructure, coordination, and research capacity.

Analytical extension

A related analytical extension aligns the five usable household datasets, extracts comparable six-hour windows, applies principal component analysis, and groups recurring environmental profiles with k-means clustering. This next phase connects the field-research lessons to a reproducible workflow for interpreting irregular multivariate sensor records.

PCA-reduced observations grouped with k-means reveal recurring short-term environmental profiles.
