摘要
A system for monitoring a concentration of carbon dioxide (CO2) in an unsaturated zone of a site in which CO2 should be stored under the ground is provided which includes: a plurality of apparatuses for detecting the concentration of CO2 in the unsaturated zone, each including a cylindrical chamber buried in an unsaturated zone under the earth surface, gas introduction holes formed in the side surface of the chamber, and a CO2 concentration sensor formed through the top of the chamber so as to measure the concentration of CO2 contained in the gas in the chamber; a plurality of communication devices transmitting the CO2 concentration output from the CO2 concentration sensor; and a monitoring server storing a reference CO2 concentration every time zone and comparing the reference CO2 concentration with the measured CO2 concentrations transmitted from the communication devices to output a normal signal or an abnormal signal.
