A Quadcopter for Monitoring System of Carbon Monoxide Levels Based on Internet of Things

The system is designed to be able to monitor the concentration value of Carbon Monoxide (CO). This system uses a modified quadcopter so that measurements can be made by mobile. Measurement of CO concentrations was carried out using the MQ-7 sensor and utilizing the u-blox NEO-6M GPS Module to determine the CO measurement location point. Based on the research conducted, the concentration of carbon monoxide gas can be measured in the range of 20-100 ppm. System testing is carried out by flying the quadcopter at an altitude of $\le$4.54 m. The test results show that the CO concentration value has been successfully loaded in the form of an interactive map on a web page that can be accessed online.
