A Low-Cost Air Quality Tracking System Design

Environmental contamination has posed a significant threat to the development of society and human survival. The majority of indoor air quality measurements are above the healthy level, making it difficult to maintain a productive and stable environment. As people spend the majority of their time indoors, Indoor Air Quality (IAQ) has a direct impact on human health. With the emerging digital world, more sensing devices are incorporated in performing the day-to-day activities. In this scenario, crowd monitoring is currently considered as the most suitable solution in this situation, allowing for distributed, cooperative, low-cost, and precise control of air pollution levels in congested urban areas. This study integrates the crowd sensing technologies with low-cost electrochemical sensors for monitoring the air quality, as well as the requirements for equipping individuals with air monitoring qualities.
