Remote Air Quality Monitoring System by Using MyRIO-LabVIEW

Air quality monitoring is essential to ensure that the places we work or live in are conducive for our health. Recent technologies have enabled remote monitoring of the conditions of our environment such as air and water. This paper presents a remote air quality monitoring based on myRIO-LabVIEW, which could monitor the quality of air via detection of Carbon Monoxide (CO) rate in indoor locations within buildings. The sensor use to detect the CO is the MQ-7 sensor that is connected to the Arduino Mega and MyRIO controllers; the outputs is processed by the LabVIEW software on the user computer remotely. For the purpose of testing, the system was tested at three selected locations to detect the rate of change of CO for over an hour. MyRIO will continuously save the CO rate data when the substance exists around these locations. In this way, the LabVIEW can process and display the data to the user wirelessly or remotely. Subsequently, the average CO rate could also be calculated. The system is working successfully as its detection and data logging by both hardware and software is functioning wirelessly and the result can be analyzed further by the users.
