Design and Analysis of IoT Based Ionizing Radiation Monitoring System

摘要

Continuous monitoring of radiation is essential for a location to protect its inhabitants from serious health hazard. It is also important to analyze the impact of radiation on the environment. We have developed a low-cost portable IoT based system which is comprised of a Geiger counter, Wemos microcontroller, temperature, humidity, and light ambient sensor and an online database. We have collected radiation data along with temperature, humidity and light intensity at different time frame in different weather in Chittagong City. These data can be stored and observed live from the web interface. We found that in sunny weather radiation is as high as 3000 microSieverts during the afternoon. The correlation between the measured radiation, temperature, humidity and light intensity are studied.
