Abstract

Indoor environments are described by a few contamination sources. As people normally spend over 90% of their time chance in indoor environments. Thus, indoor air quality (IAQ) is perceived as an important factor to be controlled for the occupants’ health and comfort. This project describes the system (IAQ), a low-cost of alert notification of indoor air quality level system, developed using Arduino, GSM modules, buzzer, LCD display and gas sensors. In this project, MQ7 gas sensor are used to monitor and detect the concentration of carbon monoxide in indoor air respectively. This system is program to give an alert notification when the indoor air quality goes down beyond a certain level, means when there is sufficient amount of harmful gases are present in the indoor air like carbon monoxide, CO. It will show the indoor air quality in PPM on the LCD display and buzzer is used as the alert system and will sending a message to a particular party on GSM system. The results reveal that the system can give an effective indoor air quality assessment to prevent exposure risk. In fact, the indoor air quality might be extremely different compared with what is expected for a quality living environment.
