Development of IoT based meteorological and environmental gamma radiation monitoring system

Abstract

Internet of Things (IoT) is an interconnection of various devices for collecting and exchanging data over network. Application of IoT includes many domains such as environmental monitoring, smart home, smart energy monitoring, healthcare, agriculture and smart transportation. In this paper, we propose a design of meteorological monitoring and environmental gamma radiation monitoring system for early detection of radioactive material in the environment. The study consists of system architecture, development of Arduino-based gamma radiation monitoring device, data transfer with MQTT protocol, storage of monitoring data to database, and development of user interface (UI) for data presentation. The prototype of the system has been developed and tested around the Center for Nuclear Facilities Engineering at Serpong Nuclear Complex. The presence of radioactive material was simulated using check source which emitted low dose rate gamma. The results were analyzed and presented, while meteorological data was compared with the monitoring result from the existing meteorological monitoring system. The results showed that the proposed system is able to detect the presence of gamma radiation source and meet the design requirement.
