Indoor air quality monitoring system using Arduino Uno in Cainta, Rizal and Pasay City, Philippines
Monitoring air quality is relevant in order to assess current condition of a surrounding since it has a big impact for the occupant's health. Considering that we spend about 90% of our time in indoor environments, it is very important to monitor indoor air quality in real time to detect problems in the quality of air and ventilation system. This paper aims to compare the indoor air quality in Cainta, Rizal area and Pasay City area by using Arduino Uno and MQ-135 sensors with the use of Internet of things (IOT). The air qualities in two areas are measured for 24 hours, and monitor the changes in parameters such as CO, LPG and ethanol. The areas still shows good air quality index, sudden changes only occur by sudden exposure of chemicals near the sensor such as air freshener. Increase rate of ventilation is primarily solution to prevent possible health issues.
