Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a flow oxygen full-range measurement sensor module. Background Technique

[0002] Gas detection sensor devices are widely used in fields such as household propane gas detectors and automobiles, and can detect specific gases contained in the atmosphere.

[0003] When the existing sensor module detects the oxygen content in the gas, it needs to be used in conjunction with a processing board and signal cables to complete the detection of the oxygen content and gas flow rate in the gas. During the use of the cables, the cables need to be pulled, and then data is collected. However, the cables are extremely prone to bending and damage during the pulling process, which affects the normal transmission of data. Moreover, if there are a large number of impurities in the gas during the transportation and detection of the gas, it is easy to cause detection errors. Therefore, we propose a flow oxygen full-range measurement sensor module. Content of the Utility Model
