Abstract

The instant disclosure provides a gas concentration detection device including a plurality of gas concentration measurement modules and a control module. The control module coupled with the plurality of gas concentration measurement modules. Each gas concentration measurement module including: a gas chamber, a signal generating unit and a sensing unit. The control module providing a plurality of clock signals, wherein each clock signal controls the corresponding signal generating unit to correspondingly generate the medium to enter the gas chamber and pass through the gas. The sensing unit outputs a sensing signal by receiving the medium, and the control module corrects the sensing signals from the sensing units to respectively obtain corrected sensing signals, and the corrected sensing signals are integrated by the control module to obtain a gas concentration signal.
