Pulse-type gas concentration measurement system and method thereof

A method of pulse-type gas concentration measurement, comprising the steps of:

• providing a sensor in a specific environment;
• sending a variable pulse to the sensor, so that the sensor outputs a first signal corresponding to gas in the specific environment;
• comparing the first signal with a plurality of chemical matter characteristics signals to determine a first identification result for the gas;
• determining a detection voltage according to the first signal;
• sending a square-wave pulse with the detection voltage to the sensor, so that the sensor outputs a second signal corresponding to the gas;
• and
• comparing the second signal with a plurality of chemical matter characteristics signals to determine a second identification result for the gas.

• determining at least one detection voltage according to the first signal, wherein each detection voltage corresponds to one of the gases;
• sending at least one square-wave pulse with the detection voltage to the sensor, so that the sensor outputs at least one second signal corresponding to the gases;
• and
• comparing the second signal with a plurality of chemical matter characteristics signals to determine a second identification result for the gases.
