Title:
GAS DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/196708
Kind Code:
A1
Abstract:
Provided is a gas detection system that can easily detect gas at maximum sensitivity without the need for calibration. This gas detection system 100 includes a plurality of sensor elements 1 and a detection unit 2. The detection unit 2 detects electrical characteristics of the plurality of sensor elements and outputs a detection signal. Each of the plurality of sensor elements 1 has, between a plurality of electrodes 12, sensitive bodies 11 having electrical characteristics that change in response to the adsorption of gas molecules G. The plurality of sensor elements 1 include a sensor element group 3 that is a group of sensor elements having different electrical characteristics between the plurality of electrodes 12, wherein at least one type of gas molecule G can be detected in common by all one of the sensor elements in the sensor element group 3.
