The online monitoring system of toxic gas levels in the Ijen Mountain area

Abstract

Mount Ijen Crater is one of the popular tourist destinations in East Java, Indonesia. Mount Ijen Crater presents a beautiful blue fire view. However, behind its beauty, the Mount Ijen area has the potential danger of toxic gases. In old time there have been casualties due to the disasters of toxic gases that appear in the Ijen Mountain area. This study developed a toxic gas monitoring system which can be accessed online through the website. An array sensor is integrated into the raspberry-mini pc, and the data is stored in the online database. The levels of carbon monoxide and hydrogen sulfide gas can be real-time monitored from anywhere via the internet network. This study can be used for an early warning system for toxic gas disasters in the Mount Ijen area.
