Abstract
A gas-detecting apparatus includes a pump module connected to a first input and a second input to intake air, a sensor module including at least one unit sensor configured to output a sensing signal in response to gas present in the air, and a control module configured to detect the gas using the sensing signal. The control module controls the pump module to intake second air by opening the second input when gas is detected in first air introduced through the first input, and determines that gas is detected when a concentration of gas detected in the second air is lower than a concentration of gas detected in the first air.
