WARM iARCH App

Arizona State University

About this app

WARM iARCH is a mobile application designed to monitor and analyze indoor air quality using real-time environmental sensor data.

The app displays measurements for carbon dioxide (CO₂), particulate matter (PM2.5 / PM10), temperature, humidity, and total volatile organic compounds (TVOCs) collected from connected indoor monitors. These values are combined into an easy-to-understand air quality index to help users assess current conditions.

Key features include:

- Real-time indoor air quality readings from supported monitors
- A unified air quality index that summarizes overall indoor conditions
- Trend analysis to identify rising pollutant levels
- Smart alerts when air quality thresholds are exceeded
- Actionable recommendations

WARM iARCH is intended for researchers, facility managers, and indoor environment monitoring projects that require reliable visibility into indoor air quality conditions. The app helps users understand when air quality is degrading and supports timely interventions to improve indoor environments.

What’s new

Improved notification settings, including reliable Quiet Hours and Critical Alert Bypass controls. Alert times now display correctly in local time. Monitor data remains accurate during temporary connection issues, with clearer stale-data indicators and no sample-value substitution. Also includes stability and performance improvements.
