Monitoring system is a system for supervising a project in progress to ensure the
project is on schedule. The MQ-7 sensor is the sensor that can sense the present of
carbon monoxide (CO) in the air. Scilab is a free software can be used to build
graphical user interface (GUI) for monitoring system in real-time. This project is
needed because CO is harmful to human’s health. This system comprises of MQ-7
sensor, Arduino UNO microcontroller and Scilab. With the interfacing of Arduino and
GUI in Scilab, the real-time monitoring system can be developed into a system that is
suitable for home or industrial use. This paper discussed about the interfacing between
Arduino and Scilab to develop a system and the application of programming for both
module. User can measure the CO concentration in surrounding air by pressing the
pushbutton on the GUI and a graph will be plotted at real-time.
