Gas detecting device

A gas detecting device for measuring at least one target gas containing at least one first gas and at least one second gas, comprising:

• at least one actuating-and-sensing module comprising at least one first gas sensor, at least one second gas sensor and at least one gas transportation actuator, wherein the gas transportation actuator guides the target gas to the first gas sensor and the second gas sensor for measurement;
• at least one driving controller configured to control actuations and non-actuations of the first gas sensor, the second gas sensor and the gas transportation actuator;
• at least one data storage device having at least one gas database, which stores reference information relative to a gas consisting of the first gas, a gas consisting of the second gas and a gas mixture including the target gas measured by the first gas sensor, and stores reference information relative to the gas consisting of the first gas, the gas consisting of the second gas and the gas mixture including the target gas measured by the second gas sensor;
• and
• at least one data processor configured to calculate at least one concentration of the target gas,
• wherein the first gas sensor measures the target gas and transmits at least one first gas measured information to the data storage device, the second gas sensor measures the target gas and transmits at least one second gas measured information to the data storage device, and the data processor calculates a concentration of the first gas and a concentration of the second gas in the target gas by comparing the reference information stored in the gas database, the first gas measured information and the second gas measured information.
