              Key Features
              
                Uniqueness: This dataset offers extensive indoor air quality
                  data from 30 indoor sites in developing Indian communities, annotated with daily activities and
                  real-time pollution dynamics, filling a gap in large-scale datasets for developing nations.
                  
                    - Multi-device: Contains pollution measurements
                      from multiple devices per site, with up to six devices in residential households, offering unique
                      observations of spread.
- Indoor types: Captures data from five types
                      of locations (residential households, studio apartments, food canteens, classrooms, research labs)
                      across 30 sites.
- Frequent pollutants: Includes readings for
                      indoor temperature, humidity, and eight pollutants (CO2, VOC, PM1, PM2.5, PM10, NO2, C2H5OH, CO).
                    
- Human annotations: Real-time activity labels
                      collected via a speech-to-text app, providing necessary context for interpreting pollution
                      readings.
- Multi-city deployment: Data from four regions
                      in India, covering rural, suburban, and urban populations.
- Dataset duration: Data collected over six
                      months (Summer and Winter), capturing seasonal pollution dynamics and behavioral variations.
Potential Applications: In general, the dataset can be used in
                  the following applications.
                  
                    - Pollution Source Identification and Activity
                            Monitoring: Records instances of pollution patterns with specific
                      activities, aiding in source and activity classification.
- Analysis of Spreading and Accumulation Patterns in
                            Different Floor Plans: Useful for studying pollutant spread and accumulation in
                      varied room structures.
- Healthy Home Characterization and Indoor Design
                            Improvement: Helps identify features to mitigate pollution spread, supporting
                      healthier indoor designs.
- Smart Device Control: Enables design of
                      control policies for ACs, exhausts, air purifiers, and other ventilation devices.
Benchmarking & ML Applications: Enables research in pollution
                  source detection, activity classification, pollutant spread in varied floor plans.
                
Dataset Size: Includes 89.1 million samples over six months,
                  with 13,646 hours of air quality data and 3,957 activity annotations.
