Monitoring Indoor Air Quality by using IoT Technology

Millions of people worldwide die prematurely as a consequence of air pollution. Many of these deaths occur in large cities, where exhaust from cars, factories, and power plants fills the air with hazardous particles. Indoor air pollution can be higher than outdoor concentrations up to ten times due to incorrect functionality of heating, ventilation, and air conditioning (HVAC) system. Internet of Things can help to perform a real time monitoring of indoor air quality by using embedded electronics, software, sensors, and connectivity. One approach that is gaining momentum is the Web of Things, that uses web architecture and web standards as a framework for creating IoT applications. In this paper, an IoT platform for monitoring indoor air quality is presented. The implementation is based on the Web of Things concept and uses CoAP protocol to collect data from sensors. Hardware platform developed for this project is also presented and implementation details are described.
