Problems solved by technology

However, gas sensors on the market can only measure a single type of gas. For multi-component gases, a combination of multiple gas sensors is required to measure. Compared with a single gas sensor that can simultaneously measure multi-component gases, the cost is greatly increased. The volume is also relatively large

Abstract

A multi-component gas sensor is provided. The multi-component gas sensor includes an electronic control unit. The electronic control unit is connected to a heating unit, a Pt10 heater and metal oxide sensitive members. The heating unit is connected to the Pt10 heater. The metal oxide sensitive members are laid on a ceramic heating substrate, and the ceramic heating substrate is adhered to the Pt10 heater. The sensor includes a plurality of the metal sensitive members. In the structure, the Pt10 is adopted as a main part of the heater and is adopted as a thermistor, heating temperature values can be feed back in real time through resistance values of the thermistor, and then various components in gas to be detected are detected through the metal oxide sensitive members.

Description

technical field [0001] The patent of the present invention relates to the field of gas sensors, in particular to the field of sensors capable of simultaneously detecting multi-component gases, and specifically refers to a multi-component gas sensor and a gas detection method for multi-temperature time-sharing measurement. Background technique [0002] A gas sensor is a device that converts information such as gas composition and concentration into information that can be used by personnel, instruments, computers, etc. It can convert a certain gas volume fraction into a corresponding electrical signal. The response curve of the gas sensor to different gases is the basic basis for the sensor to detect the composition and concentration of the target gas. The output of the gas sensor is affected by two key parameters, the composition and concentration of the gas. The gas sensor has different curve response change rates for different gas compositions. , the gas concentration is t...
