Real-time monitoring system is a system that allow user to make regular observation
and recording activities on a project or programme in actual time. The MQ-7 sensor is
used to detect the presence of carbon monoxide (CO) in the surrounding air. Cayenne
is a freeware used to allow user to monitor the activities of their project using
smartphone. This project is needed because CO is a silent killer. The objectives are to
find the relationship between CO concentration and the output voltage of the MQ7
sensor, develop a program to measure CO and send the value to smartphone and
design the GUI using Cayenne on smartphone to monitor the changes of CO value.
The sensor was studied and tested before the programing for the microcontroller is
developed. Then, the GUI was designed on Cayenne and the whole system was tested.
Finally, a real time CO monitoring system is developed.
